The Classic Freezable Lunch Box is the only horizontal lunch box with PackIt's patented ECOFREEZE TECHNOLOGY: freezable gel built into the walls of the lunch box. The smart design eliminates the need for separate ice packs or gel packs. Imagine that, a lunch box designed to be frozen. It's freezable, it's reusable and it actually cools. It is designed for bentos like our new Mod Lunch Bento or Mod Snack Bento containers with room for a drink and extra snacks. The buckle handle clip is convenient for travel to and from school, daycare and sports activities. Gel-lined walls chill a meal and a 12oz (340ml) drink for hours (depending on external temperatures). Measurements: Open: 10 x 4.5 x 8 inch, Flattened: 10.25 x 2 x 8 inch.
