WORLD-BIO Shipping Cold Packs Dry Ice for Shipping Frozen Food, Flexible Cold Ice Pack Sheets for Coolers, Long Lasting Freezer Ice Packs 14'' X 13'' 144Cells

Keeps my pre-cooled drinks cold enough inside the cooler and doesn't 'sweat' a lot. Good value for money.

These work great but they do deflate after maybe 8-10 uses and you will have to replace them. Still cheaper than buying ice each time and they do stay frozen for a good while. I use them in my cooler on day trips , because they don't make a water mess like Ice does. Make sure you soak them well before you freeze them and if you stack them in the freezer, put a freezer plastic bag (or any plastic bag) between each sheet or they will stick together and depending how badly they stick, they can rip when you try pull them apart

RV refrigerators just don't cool like a house model, especially if you're on the move often. These cold packs are not real dry ice, but they are the best reusable cold pack I've seen. They are flexible, which is super for wrapping around the milk or other cold food items during relocation. They are reusable so I'm saving money buying ice. They are thin, taking up little of the already tiny amount of freezer space we have when they need refrozen. There are multiple sheets that allows for circulating the frozen ones.

Same as above

I was looking for a dry ice to keep my deli meats, fruit salad and condiments cold with out having ice melt and getting everything wet.It worked perfectly, I cut the sheet to line and layer the cooler . I used the cooler for 14 hours and the dry ice packet kept everything cold . And they’re reusable! Great purchase just what I needed.
