When you want to pack a lunch or snacks for an outdoor outing or road trip where there might not be any refrigeration handy, these Gel-Cool Bento Boxes will ensure that food doesn’t spoil, especially in hot weather. The BPA-free plastic containers have an ice pack built right into the lid, and you simply store the lid in the freezer overnight, then pack your food to go the next day. The boxes will keep the food cold for up to four hours, especially helpful for things that spoil quickly and become unsafe to eat when exposed to heat.
