JoyJolt Savor Fluted Coffee Glasses

Yes, the double-walled construction creates an insulating air pocket that significantly slows heat loss compared to standard single-wall ceramic mugs. This design also prevents condensation on the exterior, keeping your hands comfortable while the liquid stays hot.

Absolutely. These glasses are crafted from heat-resistant borosilicate glass, making them fully microwave-safe for reheating your beverage.

While the fluted design adds a sophisticated aesthetic, the glass is smooth and easy to wipe down. Because they are dishwasher-safe, you can also let your machine handle the cleaning without worrying about the texture trapping residue.

Borosilicate glass is specifically engineered to be more resistant to thermal shock than standard soda-lime glass. This makes the mugs less likely to crack when exposed to sudden temperature changes, such as moving from the freezer to the microwave.

Each mug holds 13.5 ounces. This size is ideal for a standard cup of coffee, a large latte, or a generous serving of tea.
