U-Konserve Stainless Steel Insulated Food Jar

Keep food hot or cold for hours with this stainless steel insulated food jar, perfect to take with you on-the-go or to keep food hot in lunchboxes!

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 these double-walled food jars.

Similar to a thermos, the U-Konserve Insulated Food Jar is double-walled and vaccuum insulated to keep food piping hot. To use, pre-heat with very hot water for a few minutes before adding hot food, or pre-chill in the freezer for a few minutes (lid off) before adding cold food. This food jar will keep pre-heated food hot up to 5 hours and pre-chilled food cold at least 8 hours.
