Handmade ceramic tumbler made of white stoneware glazed sea blue on the inside and outside. Perfect for keeping drinks cold in summer, hot in winter, as clay insulates your drink.

Dishwasher, microwave, and oven safe.

Wheel thrown, hand trimmed, bisque fired, dipped in lead-free glaze, and fired to 2167 F. There are small variations in each tumbler, because they are handmade.
