## Description

U-Konserve Insulated Food Jar Stainless Steel Container is leak-proof and keeps food hot or cold for hours! Pack soup or chili in the morning and lunch will be steaming when you are ready to eat. Pack smoothies or yogurt and it stays cool until lunchtime. Take leftovers on-the-go so you can eat healthier and reduce food waste with our double-walled food jars. Similar to a thermos, they keep the temperature you start with, so pre-heat with very hot water for a few minutes before adding piping hot food, and pre-chill in the freezer for a few minutes (lid off) before adding cold food. Our food jars keep pre-heated food hot up to 5 hours, and pre-chilled food cold at least 8 hours. Dishwasher safe. Exterior stays room temperature and condensation-free. 304 (18/8) stainless steel, silicone seal. Free of BPA, BPS, phthalates and lead. 12oz, 5.25" x 3.5". Remove all sticker before washing.

## 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.
