They get cold, they stay cold. Size is very good, too.

Great for all lunch containers! I use them with bento containers and others as well.

Good size, compatible with bentgo lunchboxes. Easy to wash.

They fit well in my bentgo lunch bag and do what they need to.

Fit perfectly lunch box, 2 of them, and way to clean

I like the slim design of these. They fit easily in both my freezer and my kids lunch bags.

Fits perfectly in the Bentgo lunchbox highly recommend.

Thin and work great. How much can you really say about ice packs?

I love these products! They are all well thought out out and high quality.

I can fit these and more into my Bentgo lunch bag.
