Blue Ice Packs for Coolers, Shipping and Lunch Box, Slim Size Long-Lasting Reusable Ice Pack, 4" x 4" Cold Gel Freezer Packs for Camping, Beach, Fishing, Shipping Food

Perfect size ! I use some for lunches. Some I put separately for use on body, sore muscles, etc. I like that I don’t have to freeze them all at once. Great product for the price.

Initially I was skeptical upon opening the package, but found them easy to use, bloom in water as instructed. The smaller size freeze in a short period of time, making them very functional for lunch boxes. The outer shell is durable enough for reuse, overall a good value.

These are really nice but smaller than I thought they'd be, but they worked out perfectly for a different use. They're perfect. Boo boo size very durable and you can freeze them over and over

These are good for up to 5 hours if just sitting outside in shade. They don't leak, they fill fast with water and its easy to fill up and stick in freezer the night before use. they are perfect size to fit in between my 4oz cookies when I have my stand open. they can be a bit thick but if you want them flatter just let them sit in water for a shorter amount of time and flatten them a bit before freezing. There are a ton in the package so I usually put half of them out at my stand, and when they start to unfreeze too much I replace them with the other half. Mind you, I use them outside in 85-90 degree weather, not in a cooler. They may last longer in a cooler but this works for me.

They keep longer than I've and they refreeze great. I'm a flight attendant so when I do get a hold of dry ice it's refreezes these packs so well too! They also refreeze quickly in the freezer when I'm short on layover time or turnaround time at home. You can choose how thick they get by how long you let them soak in water when you first set them up. Be prepared to soak and freeze before their first use. They don't come frozen (which would be strange if they did but nevertheless an easy to make assumption).

Pretty cool and they work great, the seams burst easily and they leak. But it is more like a textured gel that comes out in clumps. So easy to clean up. But probably cannot use more than 3-4 times before we noticed them start to burst

Initially tho8ght they were great. After a few cycles of freeze and thaw they burst and go in the trash

Ice packs are amazing they stay cold for a very long time! No leaks! Great for keeping waterbottles and food cool. And they don't rip easily use them very often and still great

The ice packs work extremely well. Read the instructions to quickly set up the ice packs for enjoyment. I almost eturned the product until I read the instructions

I tested a packet just to see if it was actually 48 hours lasting…. It’s about 10 hours only. I know cause I timed it.

These are tiny. You have to soak them in water. Would give 0 star if I could.
