The KOSANJI Case — a 65% exploration of marble as a mechanical keyboard case. Carrara White or India Green, shaped, polished and sealed in-house for a refined, desk-ready finish. Every piece, by nature, unrepeatable.
There is something deeply considered in the Japanese approach to craft - treating tools with intention, allowing materials to guide the process, and accepting that refinement takes time.
Working with stone forced that mindset. It doesn't bend easily to direction. It reacts, resists, and asks for patience. Precision meets unpredictability — both the challenge and the appeal.
Each case is shaped in-house from a single block — natural variations in grain and veining making every KOSANJI case visually unique.
Quarried in the Carrara region of Tuscany, Italy, this marble has been used in sculpture and architecture for centuries. A clean white base with soft grey veining — refined, subtle, timeless.
Quarried in Rajasthan, India, India Green is known for its deep forest tones and layered mineral movement. Visually striking, but still balanced — a darker, more expressive take on the KOSANJI Case.
