This tumbler is telling you what you already suspected -- it's just menty b!
Tumbler is handmade from porcelain clay and measures approximately 3" in diameter and stands around 5" tall. One of a kind.
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.
