This U Konserve 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 grain bowls and it stays cool until lunchtime. Take leftovers on-the-go so you can eat healthier and reduce food waste with this double-walled food jar.
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. These food jars keep pre-heated food hot up to 5 hours, and pre-chilled food cold at least 8 hours. It has a plastic-free, stainless steel interior, and is double-walled and vacuum insulated. The lid's interior is stainless steel (with a silicone seal) that is leak-proof and airtight. The exterior stays room temperature and condensation-free.
Care Instructions: Hand wash only.
Made of 304 (18/8) stainless steel, seal is silicone. BPA-free, phthalate-free and lead-free.

With proper care, these should last forever. But since they are stainless steel, they can be recycled at a scrap metal facility.
