This exquisite piece combines elegance and grace, achieved by applying a traditional technique of painting patterns with gold and silver leaf or powder on stainless steel, then coating it with lacquer. It seamlessly blends into modern living spaces. The Shi-ma series' red urushi-nagashi rocks cup is a double-walled stainless steel rock cup, perfected by the four masterful techniques of Tsubame-Sanjo's polishing, Ishikawa's traditional Yamanaka lacquerware painting skills, Kanazawa's foil beating technique, and Echizen's washi paper making. Shi-ma rock cups are available in three colors, each offering its unique charm. You can find more details on the other Shi-ma product pages. Enjoy the collaborative artistry of Japan's four major production areas, along with the lingering taste of victory. 【Caution】 * Not suitable for dishwashers, microwaves, or ovens. * Avoid prolonged immersion in water for storage. * After use, hand wash and wipe with a soft cloth.
