From Shizuoka

Besides all the big pen companies there are always some much smaller brands doing their best to stay alive in a very competitive market. In Japan we have already seen the case of Eboya and Onishi, and I have also mentioned brands as Ohashido, Stylo-Art Karuizawa and Hakase. But there are more.

Masahiro Seisakusho is the brainchild of Narihiro Uchino (内野成広). It is a small company located in the city of Shizuoka, about 150 km South-West of Tokyo. Its pens are only sold on-line through its own website, which happens to be only in Japanese (and very confusing on top of being in Japanese), thus limiting the distribution and visibility of the brand.

Masahiro Seisakusho.

Masahiro pens use Pilot nibs in sizes 5, 10, and 15, and no effort is done in hiding its origin. In fact, Masahiro Seisakusho is also a selling agent for Pilot pens. But Masahiro Seisakusho makes a point of making custom ebonite feeds for its nibs instead of using those manufactured by Pilot in plastic.

Ebonite, indeed, is the signature material of Masahiro pens. Most of its pens are made of this material, which is imported (presumably from Germany) instead of sourcing it from Nikko Ebonite, as all Japanese makes do save Hakase. However, Masahiro also produces some pens in acrylic plastic.

As for the filling systems employed, cartridges and converters (Pilot proprietary) are reserved for the lower cost models. More expensive models use the so-called M-system, which is nothing else than the old A-system implemented by Pilot in the 1950s on some 53R pens. This system, a pulsated piston, is the obvious predecessor of the Pilot’s CON-70 converter.

The pen whose pictures accompany this text is a fine example of all those characteristics: ebonite body, Pilot’s size 10 nib, A-system filing mechanism…

Its price was JPY 40000 in 2012. Since then, its price has increased greatly—JPY 98000.

My thanks to Mr. NK.

Hablando del rey de Roma. Ya vez tu que cosa mas exquisita y bella. Quizá las fotos no le hagan honor, pero parece con vetas verdo-azuladas y negras??. Es un trabajo maravilloso, más allá del interesante sistema de llenado. Nuevamente felicidades.

En mi opinión, el color de la ebonita es verde y negro.

Gracias, Leonardo, por pasar por aquí y dejar un comentario.
