MR.ICE Dry Ice for Shipping Frozen Food 15 Packs - Cold Packs for Shipping - Dry Ice for Drinks Coolers Dry Ice Packs - Freezer Packs for Lunch Box - Long Lasting Ice Packs, 6.9" x 4.7"

I was making a 10 hour trip with my granddaughters' birthday cakes and cupcakes and needed to keep everything cool. Ice packs plumped in under 3 minutes in water and froze overnight. Packs partly defrosted in the coolers on the trip but kept everything cold. Great buy! Dont let them touch as they freeze or they will stick together. My only complaint is they don't dry up to put away. I left one sitting out for three days because it popped opened and it never dried up.

They kept cold for a great length of time. Next time I use them, I would probably not fill them up with water as much because it wasn’t really comfortable trying to fit them in when they were about the size of a pop can. Would probably try to get them flatter next time. But overall effective. Would get them again.

These worked great! But don't soak them as long as the label says- the ice packs will expand in the freezer and if the pack is too plump it will leak some of the gel from inside. I tried the first one as directed, then course corrected and only soaked the others for about 1 minute. All worked great-

When I received this thin package, I thought they had sent only one. No, there are several sheets, very thin. I placed one in a bowl of water, and holy moly! In a couple of minutes it was very full! I froze it overnight, and it is a great ice pack. And I’ve got several more once this one wears out, which is apparently going to take awhile. I’ve been using it as a sleep aid to keep my neck cool at night. It’s still mostly frozen in the morning and I refreeze it for the next night. Great product, and value!

I would give a 5 but the first 5 of them I froze burst. I was almost afraid to try the rest. But I did and they didn’t bust. I still have them.
