Description
The Eboya Kyouka Medium in Kunpuu Green highlights the distinct design of this particular pen line. Crafted by Eboya—a boutique Japanese brand—this model stands out as one of their most celebrated offerings. It comes fitted with a 14k solid gold nib of your choice and qualifies for complimentary nib tuning and optional customization services.
With its rich green hue and minimalist cylindrical shape, the Kyouka model offers a refined aesthetic that has become a signature of Eboya’s craftsmanship. This Medium-sized version is well-suited for a wide range of writers, while those who lean toward larger writing tools may prefer the Large version. Conversely, the Small variant is ideal for users who appreciate compact pens.
Eboya operates as the artisanal division of Nikko Ebonite, a company known for supplying ebonite—a natural hard rubber material—to Japan’s premier pen makers. The ebonite used in these pens originates from the sap of the Asian rubber gum tree and has long been cherished as a premium material for fountain pens. Its durability is evident in the many vintage pens made from ebonite that are still functional a century later.
The appeal of Eboya pens extends beyond the material. The nibs are produced by Bock, the German manufacturer trusted by top European pen brands. These 14k gold nibs offer exceptional writing quality and serve as an excellent foundation for custom grind options.
If you’re interested in nib modifications like Architect Point, Cursive Italic, or Stub, broader nibs tend to yield the best outcomes. For enhanced flexibility, finer nibs are generally more appropriate.
This fountain pen utilizes a cartridge-converter system and is compatible with both standard international cartridges—short or long—and standard international converters.
