This stainless steel leak-proof insulated thermos with an all-stainless interior 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 triple-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. U-Konserve insulated food jars keep pre-heated food hot up to 5 hours, and pre-chilled food cold at least 8 hours.
