They’re lightweight and non-toxic, and I love that I don’t have to deal with actual dry ice or special handling.I typically pack 2–3 in an insulated mailer, and everything arrives in great condition—even in summer.Pros:✔️ Easy to activate and freeze✔️ No leakage or mess✔️ Keeps items cold for long shipping windows✔️ Recyclable and disposable✔️ Perfect size for small and medium boxesCons:➖ Need time to soak and freeze in advance➖ Not meant for long-distance shipping without insulationOverall:Great value and very effective for short to mid-range cold shipping. I’ve reordered several times and will continue to use them for my small business!

Yes they held up in my ice chest almost 24 hours. Need lots to keep milk cold, so be sure to see what you are keeping cold so highly perishable items are covered.

Luna Dry Ice is amazing-REUSABLE dry ice without the high recurring cost and dangers. No freezer packs from my extensive collection compare. Luna packs are easy to prepare, lightweight and do not make a wet mess. They stay frozen for an amazing amount of time. Lunas keep food/drinks well chilled much longer than any other ice packs. The expanded size choice is appreciated. Highly recommend!

These are mini ice packs in a sheet. There is a porous membrane material side and a plastic side that make up a pouch filled with insta-snow powder. Once activated with water, the snow fluffs up into a gel that once frozen will retain the cold. My daughter ran it under the tap for 45 seconds and squished the inside around to throughly mix the powder and get a good reconstitution. We then blot dry and put it into the freezer overnight. I like the functionality of being able to break them apart into little pieces to put in various container sizes. In this case, we used it for a picnic so I kept the full sheet. During the hike, kids got hot so they took pieces of this and each one had a nice cooling ice pack, and because of the soft membrane side, they were able to put it on their skin with feeling cold burns. At the end of the day, this is put back into the freezer for next time. It seemed study as the pack didn’t burst open or leak, even with the kid’s tossing them around and playing with them. The ice in the picnic basket stayed frozen for a few hours, and then was able to still maintain cooled temperatures for up to 6hours in total (as a whole unit), the pieces the kids took apart to play with only lasted 1.5hours before it was no longer cold. Good value for the number of sheets you get. Worth it for everyday use for lunch bags, boo boo packs, quick cool off, fevers, etc.

These little ice packs are great, although they do get a little gummy as they defrost. My only major complaint is that they used to sell a bulk pack of 600, and I use a lot of these for shipping, and now you can only buy the 120 package, which isn't as cost effective, so I wish they still had a larger pack for those of us that need a lot.

Awesome ice packs! Kept everything icy cold without the melted water mess! We loved the size of these packs because you can slide them into gaps and spaces easily. Highly recommend!

Just the right size, they freeze fast and fit perfectly in my packages.

They were easy to “inflate” and freeze but as soon as I went to use them they all came apart into individual pieces, no longer a sheet as I had wanted. They did stay cold and was helpful in our cooler to keep things cold, but they were unfrozen by end of the day in an insulated cooler. On subsequent days we used the small individual pieces shoved down in between items while we used other vendor ice sheets.
