Collapsed:
The Freezable Bento Box Sleeve collapses into a compact size for ease of storing.
The entire bag goes in your freezer overnight (12 hours) to activate its built-in freezable gel. By morning, the walls of the bag will be completely frozen and ready to chill just like a fridge.
Expand your Bento Sleeve and pack your pack your food. Because the cooling is built in, you have the right amount of space to fit a PackIt reusable container or a container that is 9.4"L x 6.1"W x 2"H. Now they’ll stay cool and fresh all day!
