Bentgo Kids Chill Leak-Proof Lunch Box.

Its leak-proof seal prevents messy spills, even with yogurt or applesauce, while the kid-friendly latch makes it easy for little hands to open and close. The durable outer shell is built to resist drops and cracks, making it ideal for school, daycare, or on-the-go adventures. The tray is microwave and top-rack dishwasher safe, and the outer container and ice pack can be hand-washed for quick cleanup.  Condition: New, never used. Be sure to zoom in on the photos because my opinion of a minor wear may not be the same as yours, although I do mention anything that visibly stands out or causes an item not to function properly.
