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

I had never tried these before and they worked really well in my lunchbox. I like the size and can put two or thriee in my bag rather than one heavy bulky one...

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.

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

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).

Really small and they did not last like advertised

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!

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.
