The bear print double-walled glass has the ability to go straight from a freezer to an oven rack without cracking, thus exhibiting the thermal shock resistant property. For you, this means you can pour boiling hot water, tea, coffee, milk or ice-cold aerated drink into the cup without worrying about shattering or cracking the glass. The glass is a significant upgrade from a traditional glass as it has a double wall design that not only looks chic but also provides durability.
