"The PackIt Classic Freezable Lunch Box is the only lunch box with built-in cooling that chills food and drinks for hours. The secret is a freezable non-toxic gel liner that's integrated into the walls of the lunch box. The design totally eliminates the need for separate ice or gel packs. To use, simply flatten the lunch box and place it in the freezer for 12 hours. With fully frozen walls, this lunch box keeps food cool longer, which means you can pack healthier foods that would spoil in other lunch boxes. The Classic Freezable Lunch Box easily fits an entire meal along with a 12-oz. drink. A top-load design makes this lunch box simple to pack, and its kid-friendly zippered closure locks in cold, dry air. A slim exterior zip pocket is perfect for lunchbox notes, ID cards, napkins, or wipes. A buckle handle lets you clip the lunchbox onto totes, backpacks, or sports bags.
