The Thermos Funtainer 10oz food jar is a vacuum-insulated stainless steel container designed specifically for kids, perfect for parents sending hot soups, pasta, or cold yogurt and fruit to school. Its 10-ounce capacity suits child portions, and the navy color adds a fun, appealing touch without distracting patterns.

Standout features include Thermos vacuum insulation that keeps contents hot up to 5 hours or cold up to 7 hours, though real-world tests from users show reliable warmth for 3-5 hours, ideal for lunchtimes. The push-button lid opens easily for small hands, and the integrated folding spoon stores neatly in the lid, ensuring kids always have a utensil. Reviewers praise its performance for mac and cheese or oatmeal, noting it transforms packed lunches into enjoyable, fresh meals.
