The ceramic jaw-dropping coral Tumbler is handmade from Porcelain clay. Each tumbler is dipped in a custom blend of four glazes, to create the beautiful desert palette. The special edition tumblers are finished in a 22k gold luster rim, making them perfect as a special pottery gift! Tumblers measure approximately 3"H, 3"D and hold 8oz hot or cold liquid - perfect for cocktails or matcha! Tumblers are NOT microwavable, and hand washing is recommended.
