These tumblers are just fun to hold, whether your drink is hot or cold. Great to put them
in the freezer and then pour in your favorite summer beverage when the weather is hot. If you’re
using it for coffee, be sure to let it cool a bit because it retains the heat. The potter makes each
piece by hand which allows for slight variations. They are all microwave, oven, and dishwasher
safe. But you must avoid sudden changes in temperature (from the fridge directly to a hot oven)
because this can cause thermal shock.
