Tsuchinao Urushi Ware Stainless Steel Tumbler This is a coffee tumbler made using "urushi," one of Japan's traditional crafts. Enjoy the pleasure of holding a TUMBLER with a unique, smooth texture of urushi lacquer, different from your usual, during your afternoon break at a cafe in town or at home. The drinking spout cap has been changed to a highly airtight "screw-type." This makes it a mug that you can easily carry around.
