Designed by Tomoko Honda and Satoshi Yasujima in Yamanaka, Japan. Handcrafted by the artisans of KARMI using the advanced lathing techniques of Yamanaka Shikki lacquerware, a traditional craft in Ishikawa Prefecture. Craftsmen carve each groove by hand, and then each piece is dried over several months. The tea canister is carved from smooth Cherry Birch. The interior lid is designed to be air-tight to keep the freshness of your tea!
