Tea & Coffee Mug Borosilicate Double-Wall Heat-Resistant

✔ Resists thermal shock from boiling water: Crafted from laboratory-grade borosilicate glass, this mug safely withstands boiling water directly from the kettle without cracking, unlike standard glass mugs. This ensures durability and reliability with every use.

✔ Double-walled design keeps exterior cool: The double-wall construction provides insulation that keeps the mug’s outside comfortable to hold while maintaining the drink's temperature inside. It also prevents condensation with cold drinks, avoiding wet surfaces and drips.

✔ Clear glass shows drink colors and layers: The transparent glass makes it easy to appreciate loose leaf teas as they steep and layered coffees as they form, enhancing the drinking experience without residue or flavor absorption between different beverages.
