The jaw-dropping Ocean Tumbler is handmade from Porcelain clay. Each Karacotta 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 gift! Tumblers measure approximately 3"H, 3"D at base, 4” D at rim, and hold 8-10 oz perfect for cocktails or matcha! Tumblers are NOT microwavable, and hand washing is recommended.
