The Eboya Natsume Kunpuu Leefy Wind Medium Fountain Pen combines Japanese craftsmanship in marbled green ebonite with a 14K gold nib, delivering comfort and balance in every stroke.
Eboya, the last factory dedicated to ebonite production in Japan. Each piece reflects a commitment to traditional craftsmanship and continuous innovation. The use of ebonite—one of the first polymers ever discovered—gives this pen a unique aesthetic: ebonite is produced by vulcanizing pure rubber with sulfur (between 25% and 50%), and its name derives from ebony, which it began to replace in specific applications due to its durability and natural shine. Engraved on its body, as on all the brand’s pieces, is Eboya Made in Tokyo, a testament to its origin and excellence.
This Medium-size model stands out for its balance and comfort both posted and unposted. The Kunpuu finish—meaning “fragrant breeze” in Japanese—features a soothing green marbled pattern over a black ebonite base (an exclusive color by Nikko Ebonite Manufacturing), evoking spring’s freshness. Its surface provides a silky, non-slip touch for hours of fatigue-free writing. The precise assembly of all parts, together with the color of its ebonite, results in a piece of great beauty and quality.

Eboya is the flagship brand of Nikko Ebonite Manufacturing, founded in 1952 and recognized as Japan’s last manufacturer specializing in ebonite. For decades, it has supplied this material to leading writing instrument companies such as Sailor and Pilot. In 2009, it launched its own line of fountain pens, combining technical expertise with Japanese aesthetic sensitivity. Until 2016, production was led by master turner Noritoshi Kanesaki, a disciple of the legendary nibmeister Kubo Kohei, adding a unique artisanal legacy. Today, Eboya continues to create durable, comfortable writing instruments with an unmistakable finish.
