The Eboya Kyouka Large in Kougetsu Yellow is a pen with a commanding presence. With tones evoking camouflage or the desert at night, this is a full-sized writing instrument that is as much a superb everyday writer as it is a notable piece of design craftsmanship in its own right.

Eboya's parent company, Nikko Ebonite Ltd., provides the ebonite hard rubber for most of the major Japanese pen manufacturers. Under the Eboya brand name, their range of products includes pen pillows and guitar picks as well as fountain pens. Whatever the product line, this company displays an imaginative and innovative use of ebonite hard rubber that showcases the versatility and durability of this naturally harvested material.

Note how the decoratively knurled barrel end facilitates easy and secure posting.

Eboya pens are hand-turned from ebonite hard rubber, with color added during the vulcanizing process. The pen body is then carefully polished. Raw ebonite pens of this kind are highly prized by users and collectors, but are rarely made available by manufacturers due to the artisanal nature of the manufacturing process and the care needed at each step of production. 

Eboya pens are individually handcrafted in a process requiring a minimum of three to six months.
