## 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.
