## Description

High Quality Hand Blown Borosilicate Glass Tumbler Borosilicate glass is well known for its durability and resistance to thermal shock This means it will not crack under extreme temperature changes like regular glass. It has the ability to go straight from a freezer to an oven rack without cracking. For you, this means you can pour boiling hot water into borosilicate glass Mug without worrying about shattering or cracking the glass. While Borosilicate is far 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 shattering (it will snap rather than splinter), making clean up less hazardous 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 are being leached into your beverages as you consume them! . Double Wall Construction for Hot and Cold Drinks Double layered glass mug insulates your drink keeping it hot or cold longer while the outside stays comfortable to your touch allowing you to embrace your drink while you sip at your drink's ideal temperature.

## Questions & Answers

**Q: Will a straw fit thru the top opening?   What is the diameter of the top sip opening**
A: I’ve bought two of these at different times. The older one fit a straw easily, the newer one’s opening is much smaller, with some effort you can squeeze a straw into it but it’s jammed in very tight. Since they are glass, I think the opening size will be variable.

**Q: Will the 14oz double wall Tupkee tumbler be returning to stock ?**
A: This item was a COMPLETE waste of $$$$$!!!!!

**Q: What is the height without the lid?**
A: 6 3/4 in

**Q: If the lid is made of glass, is it possible that after 2 weeks of use the mouth of the lid changed the shape from smooth to wavy? I used hot coffee as**
A: No, for glass to change it’s shape, it would have to be heated to a temperature many times hotter than the hottest coffee.
