Thermafreeze Cryosheet 5-Pack Dry Ice Sheets for Coolers:Flat Packs for Shipping,Reusable for Coolers and Joint Pain, Ships Dry and Flat, Just Run Under Water, Hielo Seco, 9"x16.5" 5-Pack

These things are super great. They come as completely flat sheets & at first I thought they would be nothing useful. Almost returned them even !However-I needed something to lay under a potluck dessert so I tested one sheet. They must be soaked in water for not alot of time actually. I didn’t have a handy dish so I just ran water over them in the sink. Well soon enough they puffed up!Next I pop them in the freezer and try to have them lay as flat as possible. Before long they were nicely frozen, Maybe it was overnight.Used the full sheet under my dish at the picnic and it was great. It was a little lumpy but it was Bigger than my dish by a little bit so the thing wasn’t tippy. It did exactly what I needed to do -keep the dish slightly cooler than it would’ve been sitting in the hot sun by itself ! It didn’t last forever but then I wouldn’t have eaten something sitting out forever either 🤣After that first experience - cut some of the sheets into smaller squares and rectangles and use them for a variety of things.Worked in a soft sided drinks & wine cooler And it was perfect ! No dripping wet mess from melting ice- just enough to keep everything cooler. I’ve used them alot in Various coolers when I don’t have enough ice or when I don’t want the melted water.There is no worry about them freezing flat as they are bendable quite a bit when frozen. They bend enough to curve inside buckets or tuck flat alongside a case of drinks.Well worth the $$$ Have used all summer and so far holding up well even if they fall apart next year it’s still worth it compared to using fewer purchased bags of ice

We needed something to keep our food frozen during a move, these worked great! Froze them overnight then put on top of the food in the cooler to hold the temps down. So much cleaner than ice, no water mess to deal with. Since then I have put them frozen in the new freezer to help get it cold faster and wrapped some around soda bottles to get them cold faster. I will hang on to the ones I bought for cuter use instead of buying bags of ice which is throwing away money.

My wife and I had to fly from Alabama to Japan a 17 hr flight in total with over 100oz of breast milk. This product kept every bag of milk frozen and usable after at least 20hrs of being in a cooler. The only problem we had was it was not deflating after it was draining water for over day. Other than that I highly recommend and I definitely would use this again for any long flights.

Sometimes I have to work in hot environments. Two of these sheets frozen overnight and put in a carrier under my shirt have meant the difference between heat exhaustion and relative comfort

Not exactly what I anticipated since they are so flimsy. They will keep things cold for a few hours and are lightweight. Ultimately they go flat and leak.

Waste of money. Individual packets have little to no anything in them. Missed my return window, want my money back.

My son uses these for his lunches. This is the 2nd time we have ordered them

They worked out great for ice packs when you need them for pain relief on the body and keeps food cold for a long time
