Perfect for packing in a school lunch box, the compact and lightweight 10 Oz Thermos Funtainer food jar is a great choice for keeping foods and snacks at their optimal temperature. Thermos vacuum insulation technology and durable double wall stainless steel construction will keep food hot for 5 hours or cold for 7. Send your child to school with their favorite soup so they can enjoy it fresh and hot at lunch time. If they're in the mood for a cold snack, pack it up with yogurt and berries or apples and peanut butter. The wide mouth design makes it easy to fill, eat from and clean. Hand-washing recommended.
