These well-designed, casual tea tumblers are some of our favorite sipping cups. Made in Japan by KINTO, the soft curving forms fit comfortably in your hands, and the texture of clay around the rim adds a sleek touch. Made of porcelain, they hold 7oz (200ml) and measure 3.1 in x H2.6 in. We currently have: white, grey, and black available. All are microwave and dishwasher safe.
