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.

Key Information 重要情報

  Units    50 Χ Carrara White / 50 Χ India Green  Availability    Additional units may be produced if demand exceeds the initial allocation.  Pricing    Carrara White — $249 USD
India Green — $249 USD  Shipping    $50 USD for the case (wrist rest will be a little extra) I’m based in Thailand, and due to the weight, shipping is costly, but I will do my best to absorb anything above the $50 charge within reasonable limits.  Production Lead Time    90 days from the close of GB.  What's Included    1 Χ 65% marble case, 1 Χ aluminium USB port, 4 Χ self-adhesive silicone rubber feet, and standoffs.  Update**    Due to the number of recent requests, matching marble wrist rests will also be offered during the GB.  Update**    Risers will be optional. Some interested parties have requested a flat base, so that option will also be available during the GB.
