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.

The Eboya Kyouka Large Kumpuu Green is a pen that should satisfy the most demanding of big pen aficionados. Marbled swirls of green and black are quite vivid when held to the light, and the pattern fills the expansive surface area of this writing instrument.

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.

Rare among contemporary fountain pens, the Eboya Kyouka is designed to be posted. The barrel knob facilitates secure and easy posting, while the knurled engraving around the barrel end adds to the tactile and aesthetic appeal of the design. While a very large pen in posted position, the Kyouka is also extremely well-balanced - this is a pen that will be a comfortable everyday writer for many users.

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.

Bock solid gold 14k nibs are well-suited to customizations including Stub, Cursive Italic, and Left Oblique, as well as the modification for added flex - see our nib customizations page for more information.

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 ship in a simple presentation box and include a converter and starter ink cartridge.

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.
