Two of these fit perfectly in the bottom of my Bentgo lunch bag. I put my Bentgo box on top of them and still have room for extra snacks and a drink. Great purchase.

The slim size doesn't take away from the cooling power of these little bad boys. I usually use 2 inside my Bentgo lunch bags and never have to worry about refrigeration.

These ice packs have been perfect for adding to my daughters lunch box. They fit perfect in the front pocket of her lunch box due to their sleek shape and hold freeze all day long.

Skinny enough for my bag and works great. They keep food cold by the time I eat lunch which is usually 4+ hours.

Love how slim these are. They don't take up much space at all in my lunch bag and they keep my protein shakes and yogurt cold!!

These chillers are the perfect size to keep everything cold while taking up the least amount of space.

Nicely constructed and they fit inside the lunch box perfectly but they gave a chill life span of about 2-3 hours…

Perfect for the lunchbox. They are small and take up little space in the freezer but keep the food cold.

I love these Chillers because they are thinner, not bulky and allow more room for your items.I use them all the time and they do the job!

[This review was collected as part of a promotion.] It fits perfectly in my son's lunch box for school. We still have room for all of his lunch without having to decide what can't fit because of the bulky ice packs. It also stays cold longer than I thought it would with the small design.
