The Eboya Natsume Medium Kougetsu Yellow is made from hand-crafted ebonite hard rubber and is available with your choice of 14k solid gold Bock nib.

Memorable for its delicate swirls of yellow and black, the Eboya Natsume Medium in Kougetsu Yellow is both a superb example of the use of hand-turned raw ebonite as well as an exemplary everyday writing instrument. 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. As with all hand-made pens, the appearance will vary slightly from pen to pen - no two will ever be exactly the same.

The Natsume Medium size is a true mid-sized pen that will fit comfortably in most hands.

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

In contrast to the Kyouka and Ricchiku models, the Eboya Natsume features a flat top. The rich yellow and black marbling continues even onto the end cap. A gold clip can secure the writing instrument to a shirt pocket, and also acts as a built-in roll stopper.

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.

The Eboya Natsume Medium Kougetsu Yellow fountain pen 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.

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.
