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.

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.

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.

Beautiful Yuzen, even being blue toned :D
I wonder how comfortable is that Kobue grip. A section with nothing to prevent the fingers from slipping onto the nib is not usually my cup of tea. The design of the whole pen isn't either.
Is there any difference in using the gasket before or after the thread?
Thank you for this new chronicle. Always sharing your knowledge :)
I thought the same about that Kobue grip. On the other hand, I like the Hakobune... Understated elegance and a nice ebonite pattern too. But I do agree that cartridges and converters are boring.
Thanks for the post!
Thanks, Papish, for your comment. Blue pens are also beautiful!
Re where to put the gasket, it all depends how dirty your hands will become when opening the barrel to refill it.
Cheers,

R Vieira,
Thanks a lot for your comment. Let's cross our fingers hoping for new pens with more elaborated filling systems.
Thanks for passing by and commenting.
