Set of 2 Coffee Cups with Handle Handmade Insulated Borosilicate Glass Double Walled Coffee Mug 300ML

Borosilicate glass is a heat-resistant glass that is perfect for hot and cold drinks. While borosilicate glass is naturally lighter than conventional glass, it is stronger and more resistant to temperature changes and scratches. Double-walled glasses keep your hot drink hot for a longer period of time, while the outer glass feels cool. Your cold drinks stay cool inside, while the outer wall remains*of condensation.
