Description:

Our Double Wall Glass Mug is made of BPA-free and lead-free borosilicate glass (also known as hard glass). Crystal grade glass is super transparent, strong, low expansion, high heat and cold resistance, and high stability.

The double-glazed structure keeps hot drinks hot without burning fingers, while cold drinks stay cold without messy condensation. In addition, double-layered glass can keep your drink at high or low temperature for longer than single-layered glass.

The double-layer design makes the internal liquid appear to float. This glass can be used as a traditional tea cup, coffee cup for hot drinks. It is also ideal for cold drinks from cocktails to beer. The product is easy to wash in the dishwasher or hand wash.

A small vent on each bottom of the double-walled glass in the zen room to equalize the air pressure between the two layers of glass when hot or cold liquid is added. Ventilation holes increase durability and never allow liquid to enter between the two layers.
