This tumbler is serving some real talk. It's handmade from porcelain clay and measures approximately 3" in diameter and around 5" tall.
It's been fired to over 2300 degrees so that's plenty hot to be food safe, dishwasherable, and microwave safe, too. The exterior is polished to be smooth and the inside is coated in food safe clear glaze.
Handmade in Brooklyn, NY.
