Dragon Glassware Astronaut Glasses

Yes, the Astronaut Glasses are microwave safe. The double-walled borosilicate glass construction is designed to handle temperature changes, so you can safely reheat beverages without worry.

Each glass has a 7-ounce capacity. This size is ideal for espresso, small cocktails, or a standard serving of tea or coffee.

Yes, the double-walled insulation creates a thermal barrier that helps maintain your beverage's temperature longer than a standard single-walled glass. It also prevents condensation on the outside when serving cold drinks.

The iridescent finish is integrated into the glass construction, not just a surface coating, which makes it durable for regular use. However, to maintain the finish's luster, hand washing is recommended over harsh dishwasher cycles.

While the glass material is durable, we recommend hand washing these glasses to preserve the integrity of the iridescent finish and the delicate double-walled structure over the long term.
