Double wall glass coffee mugs 12.5 OZ

The double-layer glass mugs are made of 100% lead-free mouth-blown borosilicate glass, a well-known material for its durability and safety when in contact with water. It keeps hotter and colder than the normal single-walled glass and ceramic mugs. Cool to touch, without burning fingers. Our glass coffee mugs also feature a small round hole design on the bottom, which prevents the mugs from bursting during use and allows the glass to breathe during temperature changes. The hole is sealed, so water won't get in, ensuring your safety and enjoyment every time.
