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

With swirls of vibrant green and black ebonite, the Eboya Kyouka Small Kumpuu Green fountain pen is an exemplary everyday writing instrument as well as a work of art in its own right. This cartridge-converter pen takes its inspiration from early twentieth-century hard rubber pens such as the Mabie Todd, Swan, and Onoto.

Each Eboya pen is hand-assembled in a process that requires a minimum of six months from start to finish. Eboya supplies the raw ebonite stock to most of the major Japanese pen manufacturers, and their skill in the manipulation of this material is readily apparent - Eboya brand fountain pens have a unique aesthetic that is distinctly their own. Not a petroleum product, this is natural ebonite sustainably harvested from the Asian rubber gum tree.


Note as well the knurled pattern around the barrel end.

Though named the "Kyouka Small", this is actually a mid-sized pen that will be a comfortable fit for most users.


"Eboya - Made In Tokyo" is machine-engraved on the barrel.

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.

The Eboya Kyouka Small Kumpuu Green ships in a simple presentation box and includes 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.
