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 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.

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

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

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

At first I thought these were supposed to be freezer gel packs. When they came they were very small and had some kind of powder in them. I was disappointed and gave a bad review. After looking further into the product instructions, I found out I made a mistake. After you soak these in water l, they expand and freeze well. I left them in my lunch bag I take to work over the weekend in my car. They thawed, but did not leak. They're actually pretty cool. I stopped my return. My apologies! Great product!

These work really good you have to get them wet. They filled up with water. Can you put them in the freezer and the freeze in the form of you know a packet that would fit in the palm of your hand I put them in a baggie after that and I end up with my own ice pack, I use them for work for my Cooler. They work really well.

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.
