## 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.
