## Questions & Answers

**Q: Is the lid twist on or pop on?**
A: This lid twists on.  FYI when I purchased I experimented: reheated with boiling water then sealed more water in. After 12 hours temperature at 120F, so not bad AT SLL.

**Q: Is it safe to touch if i fill it with hot drink?**
A: Yes

**Q: Hello, Is the inside of the thermos lined with plastic or a nonstick material?**
A: Nope, no lining. just metal.

### ⭐⭐⭐⭐⭐ Works great
*by K***. on October 18, 2023*

Works as intended, keeps food hot. Wanted a thermos that didn't have plastic touching the food, and this fit the bill. Opening is plenty wide enough to get a spoon in to eat hot food.
