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

These ice packs are actually so cool. They come unfilled so essentially they’re empty plastic packets. You lay them in water and they absorb the water and then you freeze them. They’re good quality and perfect size for a lunch box. It’s a good value in my opinion rather than buying other ready to use lunch ice packs.

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...

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.

These work very well, but they don’t last as long as you may think. Some of the reviews were misleading, as if they last a very long time, but depending on the amount of use, they do start to open up in the back and leak and then you need to get a new one. When you first freeze them, they do work very well and keep things cold for a lengthy period of time though. I’ve had mine at work with me for up to 10 hours and they have kept items cold.

It's small, but this is a great product. I bought it to put in a Styrofoam container to ship food and it worked so well! Its lightweight, so it didn't add much to shipping cost, and other than the condensation from the melting, there was no water. And you can use them again. And I liked that I could fill them very full or not very full, and bc they were small, it was easier to fit around the space. BUT I think people will be surprised that they are so small, so look at the measurements before you buy it to make sure it's what you want.

I must have gotten a bad batch. Soaked for an hour and a half. Swelled nicely, looked good. Dried them off and put them in the freezer. Next morning, checked them and all were frozen but half the bags had burst with some of the chemical protruding out. I’m throwing them away. I don’t trust them in a cooler. I definitely don’t recommend these. A total waste of money.

These are amazing, I can choose who wide or small I need each cube. Last a good amount of time. No leaks quick shipping.

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.
