Green Insulated Food Jar | 12 oz

Price Qty.


This stainless steel, leak-proof insulated food jar 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, pasta salad, or yogurt and it will stay cool until lunchtime. 

Similar to a thermos, insulated food jars are designed to keep the temperature you start with, so U Konserve recommends pre-heating the jar by pouring very hot water inside and letting it sit for a few minutes before pouring the water out and adding your piping hot food. Prior to adding cold food, pop your food jar in the freezer for a few minutes (lid off) to cool down.
