(IC) KŌBŌ ISSHI — Exploring Stone as a 65% Keyboard

[KOBO ISSHI]

Hello Everyone,

What began as a simple curiosity with stone evolved into a two year-long obsession.

Today, I’m proud to present the KOSANJI case — a 65% exploration into marble as a keyboard.

Available in both Carrara White and India Green.

Stone Variants 石の種類

	Carrara White		A classic Italian marble featuring soft grey veining on a clean white base. Refined, subtle, and timeless.
	India Green		A darker, more textured stone with deep forest tones and mineral complexity — visually striking yet balanced.
	Each case is shaped in-house from a single block of marble, with natural variations in grain and veining — making every KOSANJI case visually unique.

Inspiration 着想

	I’ve always admired 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.

Never seen a marble case before, this is sick. India Green is calling my name. Hoping this goes to GB.
