The old-school lunch box is getting Packet's cool tech twist! The Freezable Classic Lunch Box is the only horizontal lunch box with built-in cooling that chills healthy food for up to 10 hours. You'll never waste money or space on ice packs again! The secret is a freezable gel liner in the walls of the lunch box. Simply flatten the lunch box and place it in the freezer overnight. In the morning, the walls of the lunch box will be completely frozen and ready to chill items just like a fridge all day. The Freezable Classic Lunch Box easily fits an entire meal and a 12-ounce (340ml) drink. Pack healthy foods that would spoil in other lunch boxes, such as dairy, deli meats, salads, fruits and veggies. The lunch box's long-lasting cool keeps items chilled long enough to bring home leftovers, reducing waste and saving you money. A top-load design makes it easy to pack and its kid-friendly zipper closure locks in cold, dry air. This innovative lunch box also features a mesh pocket for a small water bottle or snacks, a slim zip pocket for ID cards or wipes and a buckle handle that clips onto totes, backpacks or sports bags. All Pack It products are made from food-safe, nontoxic poly canvas and are PVC, BPA, phthalate and lead free. Simple Care: interior wipes clean, spot clean exterior. Not machine or dishwasher safe. Packet's Freezable Classic Lunch Box measures 8.25 inches tall, 10 inches wide and 4.25 inches deep while open. When collapsed, it measures 10 inches wide, 8.5 inches deep and 2.25 inches tall for easy storage in the freezer.
