Freezes so quickly and you’re able to size the packs based on what you need them for. They are scored so you can easily rip them apart to have several or just one. Kept our lunch perfectly cold the day we froze and used day 1.

I Purchased these because they claim to keep cold 24 to 48 hours. I had a 36 Hour drive ahead of me with both frozen food and refrigerated food that I had in a cooler. All of my food remained cold and frozen only partially began to thaw. Very pleased with them

Needed these for my daughter water ice stand, water ice stayed cold for 5 hours and still was rock hard even when I got home ! Definitely will buy more it’s a must get!
