JoyJolt Diner Glasses

Yes, these mugs are made from durable, lead-free borosilicate glass, which is specifically designed to withstand temperature changes. You can safely reheat your coffee or tea directly in the microwave.

The double-wall construction creates a thermal barrier that keeps your hot beverages warmer for longer while ensuring the exterior remains cool to the touch. It also prevents condensation from forming on the outside when you are drinking cold beverages.

These mugs are completely dishwasher safe. The borosilicate glass is durable enough to handle standard dishwasher cycles without clouding or cracking.

Each mug in this set holds 13 ounces, which is a standard size for a generous cup of coffee, tea, or even a latte.

While they feature a refined, clear aesthetic, these mugs are built for daily use. The borosilicate glass is known for its strength and resistance to thermal shock, making them more durable than standard glassware.
