Ebonite is made by combining natural rubber and sulfur through a chemical reaction involving heat and mixing. The result is a resilient material prized for its texture and durability.

The warm, smooth feel of ebonite makes it especially comfortable for long writing sessions. Our fountain pens are handcrafted from marbled ebonite in exclusive color blends, giving each pen a unique character and texture—no two are ever the same.

The "Houju" model features a traditional rounded form. In Japanese mythology, Houju is the sacred jewel held by dragons—a teardrop-shaped treasure said to grant all wishes. This pen pays homage to that powerful symbol through its elegant shape and serene presence.

Each Eboya fountain pen is carefully made and polished by hand throughout every stage of production. Using a traditional Japanese lathe called a "Rokuro," our artisans achieve a flawless finish that highlights the beauty of the material.
