Eboya tan-pen

Very often, speaking about Eboya implies some element of frustration—that of Eboya pens being exclusively cartridge-converters. And when not —the nominally eyedropper model Yuzen—, they still are cartridge-converters.

So, the Eboya market policy seems limited to release new models and new ebonite colors as long as the filling system did not change. And such is the case of the newer model, the tan-pen (in lower case).

The Eboya tan-pen. Only 97 mm long.

Its originality comes from its size: very small, very short; just 97 mm in length closed. And the well-known Eboya construction quality does the rest: the cap posts very securely onto the barrel. The result is a regular sized pen, even if on the shorter side. The price to pay is that it can only be inked with short cartridges (or as eyedropper).

Very secure posting. 133 mm long.

A size 5 nib by Bock. Note the new logo of the brand on the cap.

The tan-pen is certainly attractive and original, and represents a new approach to pens in the Eboya catalog. My only complain is that the company does not make it in black—you can choose almost any color but black. A black tan-pen, though, is available at sale events as a demonstration pen for potential customers, but is not for sale.

Any color but black.

These are the dimensions of the tan-pen:

Length closed: 97 mm
Length open: 91 mm
Length posted: 133 mm
Diameter: 12.2 mm
Weight: 11.7 g (dry)
Ink deposit: 0.8 ml (short standard cartridge)

The price, JPY 31200, plus taxes.

Eboya's Eyedroppers

Eboya, the pen brand of Nikko Ebonite, shifted gears in 2016. Lathe master Noritoshi Kanesaki left the company and the production moved to using a CNC lathe instead of the traditional “rokuro”. And it was at this moment that Eboya fountain pens relied solely on clean and boring cartridges and converters.

This situation came to an end, somehow, with the introduction of the model Yuzen in 2020. This pen was specifically designed to be used as an eyedropper filler, but a plain one at that, without any sealing system. And to do so, the pen implemented a rubber gasket –an o-ring— on the section to provide a tight seal when screwed onto the barrel. And the packaging includes an eyedropper and some spare o-rings.

The very elegant Eboya Yuzen.

The section of the Yuzen. The o-ring is right behind the thread.

But at the same time, the Yuzen can also be used with a cartridge or a converter.

The slightly older model Kobue is intended as a cartridge/converter pen, but its design also includes a gasket on the section, making this pen apt to be filled as an eyedropper.

The Eboya Kobue. The o-ring is visible before the thread.

Are these Eboya models the only eyedropper fillers? I do not think so—Eboya pens do not use internal metallic parts, and the manufacture is precise enough to not leaking should their barrels be filled with ink. In other words, with or without gaskets, all modern Eboya fountain pens work properly as eyedropper fillers (caution is advised, though).

This Eboya Hakobune is not intended as eyedropper pen, but it works as such (although not on the picture, obviously).

And that's the bottom line—all Eboya pens work well as eyedroppers and there was no need to create any specific model, however attractive. After all, these models do not fill the gap opened in 2016 when the last Japanese eyedroppers (and previously button fillers) were manufactured by Eboya.

Japanese Ebonite

In many a pen forum, the Pilot Custom Urushi, marketed initially in 2016, raised a discussion—what is better, a Custom Urushi or a Sailor King of Pen (KoP)?

The answer to that question depends heavily on the market where you were located. In Japan, for instance, the Sailor KoP is in general cheaper than the Custom Urushi, but that is not the case in many other markets.

Custom Urushi or Sailor King Profit Ebonite?

However, I wonder whether those two pens belonged to the same category. Sure they both implement large nibs, but the urushi layer of the Pilot sets it apart and adds some refinement the Sailor lacks both in the plastic and ebonite models. The urushi, in other words, might be enough to justify the higher price of the Custom Urushi in the Japanese market. And, consequently, an even more expensive KoP would necessarily be at loss with respect to the Pilot.

More apt to comparison, in my opinion, are the Sailor King Profit made of ebonite and the Eboya Hakobune XL. Both pens are made of ebonite without any additional coating, both sport size 8 nibs, both are full sized. And both cost around JPY 75000.

Eboya Hakobune XL or Sailor King Profit Ebonite?

Their differences are also clear. The KoP has a plastic section –the same section valid for all KoP models. The Eboya, conversely, is completely made of ebonite.

The weakest element of the Eboya might be the nib—a German-made Bock clearly labeled as such. In exchange, the feed is made of ebonite, which is something that many aficionados appreciate.

Hakobune XL's nib and feed--18 K gold and ebonite.

The problem the buyer might have is the limited distribution of these two models. Sailor seems focused on mode expensive versions of the KoP series of pens, and finding the King Profit in ebonite is very difficult lately. On its side, Eboya's Hakobune XL is not in the regular catalog of the company, and its availability depends on the supply of the Bock 380 system.

Conspicuously absent in this discussion is Platinum. And that because Platinum does not make any nib of a similar size. Platinum's strategy for luxury pens seem based on the decoration and not on the nib.

Platinum Izumo and Nakaya Cigar. Platinum's sense of luxury is associated to the decoration rather than to the nib.

And now, the decision of what to buy is up to everyone of us.

Pilot, Eboya or Sailor? Up to you.

TIPS 2020

The third edition of the Tokyo International Pen Show –TIPS 2020— was celebrated on the weekend of November 6th to 8th. This alone, in these times of virus and infections, is just remarkable. Now, how was it?

Basic prophylaxis set the limits and conditions of such a potential massive event –remember that in 2019 there were about 2000 visitors. This year's event was organized in two-hour slots –seven of them— with 100 people in each of them. And that set a limit of 700 attendees. In contrast, the number of tables was barely smaller: 60 vs. 70 in 2019.

So, there were the boundary conditions on which those 700 visitors went in search of pens... or other objects. What we found was not any different to what we had seen in 2019—a stationery salon.

By that I mean a space where shops and makers show and present their new products as opposed to a place where collectors search for that rarity, and where there is some actual trading. So, the bulk of the pen show was dedicated to new products—pens, inks, paper, accessories; and only a handful of tables displayed vintage and second hand pens. Of them, only one –shared by two well-known traders— had those pens as its basic argument.

New stuff.

Vintage stuff.

One interesting element on this event is that it acts as an exhibit of a number of small pen makers whose products are not distributed through the usual distribution channels and are not present at the traditional stationers in town. Such is the case of Ohashido, StyloArt Karuizawa, Eboya, Takayuki, Matsuda Maki-e, Laurett's, Chriselle, Tetzbo, Hirai Woodturner...

Some of those small makers with very limited distribution.

I have said in the past that the East-Asia concept of a pen show is different from those in the West, but it is a successful idea. And giving the harsh times we are facing, it is excellent news TIPS 2020 came to exist.

Kubota´s Yamada

NOTE (July 8th, 2023): There are some inaccuracies on this text: although the business Mannenhitsu-no Yamada strated in the early 1930s, the production of pens by Mr. Kubota started only in the 1980s or early 1990s. Some more informantion can be found on the following link: https://estilofilos.blogspot.com/2023/07/mannenhitsu-no-yamada.html.


There is more to Japanese pens nowadays than just the big three companies. I have written about some of the smaller companies on these pages--Masahiro, Eboya, StyloArt Karuizawa, Hakase, Ohashido, Wajimaya Zen-ni... even about the elusive Iwase Seisakusho.

But I had never mentioned Yamada Fountain Pens.

This company was founded by Mr. Yamada in Matsumoto (Nagano Prefecture) in the early 1930s. As of today, Mr. Hiroyoshi Kubota manages the operation.

Yamada pens are made to order. Ebonite is the base material, and Mr. Kubota decorates them inserting a number of materials (mother of pearl, gold, silver) and by adding elements made of buffalo horn and ivory. Some of those can be seen on the pictures of this text.

Three Yamada pens with three different decorative techniques.

Nibs and feeds are either Pilot or Sailor. On the present examples they are Sailor, although attached to Pilot converters.

Yamada pen, Sailor nib, Pilot converter. Buffalo horn and silver rings.

The main problem of Yamada pens is, once again, their anonymity. Nothing in them allows for a clear identification of the maker, and only the nibs carry any inscription, albeit misleading as these are not Pilot or Sailor products. The identification of these pens must be made through its general aspect, which is never an easy way to identify anything. The section of these pens, though, has a special and characteristic shape.

Yamada pens, Sailor nibs. And characteristic sections

But it is even worse than that--how do we contact Mr. Kubota? Yamada Fountain Pens does not have a website, and the most you can find is a postal address of the shop in Matsumoto, and a phone number.

Is this enough to keep the business running? Probably so--80 years of history speak high of the business model. Now, could Mr. Kubota enlarge the operation by becoming more accessible? Certainly so, but being a small business only that much demand he can meet.

And let´s not forget the appeal we collectors feel for the hard-to-find pen...

Japanese Eyedropper Today (II). Opus 88 Koloro

In 2016, Eboya stopped the production of Japanese eyedropper pens. These pens were always more expensive that the equivalent versions with cartridge/converter or with button filler systems—the Japanese eyedroppers were between JPY 59000 and JPY 83000, plus taxes. But despite these prices, these pens were the cheapest eyedropper in the market. The next step was –still is— the size 50 Namiki Urushi at JPY 148000.

On this scenario, the Opus 88 Koloro made its appearance in 2017.

The Opus 88 Koloro in its package.

The company Opus 88 –Jin Gi industrial Company— has been in the market since 1977. But from 1988 on its main business  was the production of OEM pens for other companies, Danitrio and Taccia among them. In the local market of Taiwan, Opus 88 sold some over-run of those OEM pens under its own brand.

Then, the Koloro model showed up in the foreign market in 2017. Its combination of an affordable price –in the range of EUR 100-- and an unusual filling system called the attention of many in the West. As I explained in the previous text, it is not that the Japanese eyedropper system was new at all, but its availability was very limited and expensive.

Nowadays, the Koloro is a family of pens that come in two nib sizes—size 5 and size 6, both by JoWo. The nibs are made of steel –no gold option--, and the feeds are made of plastic. The nib size conditions the overall dimensions of the pen. But in all cases, the filling system is the Japanese eyedropper.

Opus 88 could make these pens even more attractive by using in-house nibs or, at lest, nibs locally made. The implementation of ebonite feeds –and there are makers producing them-- would also increase the appeal of the pen. However, these two drawbacks are common to many pen companies.

These are the dimensions of the Opus 88 Koloro demonstrator of size 6:

Length closed: 148 mm
Length open: 136 mm
Length posted: this pen does not post.
Diamter: 16.4 nn
Weight: 30 g (inked)
Ink deposit: about 3 ml

In conclusion, this pen is an attractive product –well made, affordable, original— that fills a gap in the pen scene. And that is more than most other companies offer nowadays.

Japanese Eyedropper Today (I)

The so-called Japanese eyedropper system –inki-dome shiki (インキ止め式) in Japanese— was in fact invented by Onoto in the beginning of the 20th century. Those Onoto reached Japan imported by Maruzen and the system –an eyedropper with a shut-off valve— clicked among the locals. The final result was that this system was copied and reproduced by most Japanese pen makers along its history up to today.

An Onoto with the shut-off valve system. Not yet a Japanese eyedropper, I guess.

A Japanese Swan (Nobuo Ito's Swan) with the Japanese eyedropper system.

The inki-dome, however, fell out of favor by the late 1950s when Platinum introduced the ink cartridge and most other makers followed the example. Only minor makers –I am thinking of Sakai Eisuke's operations— kept the system alive till the 1980s.

A Sakai Eisuke's pen made in collaboration with Kabutogi Ginjiro (::1::). Possibly from the 1960s.

In 1985, Pilot commissioned lathe master Sakai the creation of a prototype based on the style of the Pilot pens from the early 1930s, The result was what later became the Pilot (and Namiki) size 50 Urushi, and it implements the Japanese eyedropper system.

The Pilot Urushi in size 50--a modern Japanese eyedropper. This pen is incorrectly named by many as Namiki Emperor, but the Emperor model is decorated with maki-e techniques according to the Namiki catalog.

But who else followed? Not much.

Eboya used the system for some years (::2::, ::3::), but its production relied in the know-how of lathe master Kanesaki Noritoshi. Eboya's boss, Mr. Endo, has announced the new production of Eboya pens with this system, but there are no final dates for their release.

An old Eboya (2013) from the Kanesaki time. It implements the Japanese eyedropper system. At that time, the brand name was still Nebotek.

More recently, as of 2018, the sort-lived Iwase Seisakusho also marketed some pens with the Japanese eyedropper system. These were either old incomplete pen bodies by Ishi Shoten (owner of the brand Yotsubishi) or new pen bodies made by lathe master Momose. But Iwase Seisakusho had a very brief life and very few units of it made to the market.

From California, Danitrio makes some models with Japanese eyedropper. These are usually expensive models with urushi or maki-e decoration.

Finally, a surprising actor is the Taiwanese brand Opus 88 (Jin Gi Industrial Co.). But these Japanese eyedroppers deserve a Chronicle on their own.

Updates to the Tokyo Pen Shop List

I have just updated the page Tokyo Pen Shops. This was long overdue after two years since the last time I revised it. Fortunately, the Google Map service that allow for the map is a lot easier to edit now.

The main changes are the inclusion of some shops to the list:

– Tsutaya at Ginza Six. This shop offers a regular selection of pens, plus a handful of unique models made in collaboration with Wajimaya Zen-ni. Re inks, this shop also offers a small selection of original colors on top of a solid supply of the regular brands.

– TAG – Takeda Jimuki in Gotanda. TAG is a chain of stationery shops owned by the company Takeda Jimuki. The Gotanda branch seems to be the biggest in Tokyo. Its main appeal are the TAG inks. Although these are also available at other shops (Itoya, Angers, Okamotoya,...), prices here are slightly better.

– Okamotoya in Toranomon. This is an old office supply shop newly restored as a modern stationer with a very Japanese flavor. It displays a regular selection of pens and an interesting gamut of inks, including TAG and the Korean brand Tono & Lims.

– Eboya in Arakawa. This is the shop of Nikko Ebonite to sell Eboya pens. This is the only stable place where to purchase this brand. The alternatives are regular sale events –usually at department stores in Japan-- or a through a handful of online shops.

I have also updated information on other shops: Kingdom Note (Map Camera) changed the location of the pen section. Kinpendo created a website.

On the negative side, some shops went under –Daiya Sutoa in Ameyoko--, or moved out of town –Füllhalter is now in Abiko, Chiba. I also removed all references to Pen Station, the deeply missed museum of Pilot in Kyobashi, Tokyo.

The list, as usual, is far from complete. Feel free to email me with more information.
