The Eboya Kyouka Large Kumpuu Green is made from hand-crafted ebonite hard rubber and is available with your choice of 14k solid gold Bock nib.

Eboya supplies the ebonite hard rubber used by most of the major Japanese pen manufacturers, but the pens produced under their own brand name have an appeal and aesthetic uniquely their own. Each pen is hand-turned and hand-finished in Eboya's Tokyo workshop in a process that requires six months or more.

Raw ebonite pens such as the Kyouka are highly prized by collectors and users. Care should be taken to avoid prolonged exposure to direct sunlight or extremes in temperature, but while the exterior appearance will naturally mature over time, the ebonite body itself is sturdy and highly durable.

"Eboya - Made In Tokyo" is machine engraved on the barrel - no laser is used.

Unless requested otherwise, each pen or nib you purchase from us will be carefully examined, tested, and optimized for your personal writing characteristics before it ships. See our nib set-up and optimization page for more details.

Eboya pens are individually handcrafted in a process requiring a minimum of three to six months. Consult our Eboya Availability Chart, updated weekly, to see which pens we currently have in stock, or simply to browse by model, size, or color.
