Which Lunch Box Keeps Food Hot?

To keep food hot, you’ll need a lunch box or container that is insulated, double-walled, and made of stainless steel. You can opt for an all-in-one design, like a lunch box with a built-in thermos, a kit with both a thermos and lunch box or a thermos container.

NOTE: A traditional lunch box made of plastic or stainless steel will not keep your child’s lunch hot, it needs to be made to keep foods hot (or cold).
