From Teaology comes an incredible new line of glassware that makes a bold statement. Made of durable, heat resistant, mouth-blown borosilicate glass of the finest quality, the Luna is perfect for tea and espresso lovers alike. Borosilicate glass is stronger than common glass. It is shatter-resistant and resistant to high heat. It is the same glass used in making beakers and other chemistry equipment. The double-walled design insulates drinks at their ideal temperature and suspends drinks with a unique floating effect. The glass is condensation free and does not get hot to the touch when filled with hot beverages. The Luna glasses are dishwasher, microwave and freezer safe. Measures 3" wide and 1.75" tall. 80ml volume.
