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 Eboya Natsume Large provides slightly more surface area for the rich yellow and black marbling. It is not an oversized pen, however, and will fit comfortably in most hands.

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.
