High Quality Hand Blown Borosilicate Glass Tumbler
Borosilicate glass is well known for its durability and thermal shock resistance. This means it won't crack under extreme temperature changes like regular glass.

It has the ability to go directly from a freezer to an oven rack without cracking. For you, this means you can pour boiling hot water into the borosilicate glass cup without worrying about breaking or cracking the glass.

While borosilicate is much more durable and resistant to thermal shock than other types of glass, it is glass, so breakage is still a possibility. However, when broken, borosilicate glass tends to crack into larger pieces rather than break (it will break rather than chip), making cleaning less dangerous than a typical glass.

Borosilicate glass is hypoallergenic, lead-free and unlike a plastic straw, it is BPA-free. Have peace of mind knowing that no toxins leach into your beverages while consuming them.
