IglooMaxcold Ice Blocks, Long Lasting Cold Freezer Ice Packs

It's an ice pack. It freezes and thaws at a reasonable rate. If you are looking for a fast freeze ice pack, you are also looking for a fast defrost ice pack. This thing is about an ince and a quarter thick. The amount it keeps cool is dependent on what you are putting them in. It's a cheap ice pack. Get it for small chests.

This ice pack is perfect for keeping my lunch cold. It easily lasts over 8 hours! It’s a great size for bigger lunch boxes and fits perfectly in mine. Just a heads-up: it is on the larger side, so if you have a smaller lunch box, you might want to consider a more compact option. Overall, it does exactly what I need and keeps everything nice and chilled all day!

The ice blocks are compact enough to not take up much room while staying cold and functioning well for long periods. They are a good value for the money and see plenty of use to keep things cold in the cooler while running errands on hot days.

Great deal, perfect size for smaller travel size ice chest. Great price

I bought these to use in our small lunch boxes. The instructions indicated that you can cut the sheet of cubes to any grid size; however when I did that, several of the cube packets began to empty and I had water on my counter. Therefore, I had some empty cube inserts. What was created and left has been useful and they last for several hours use.

Good icepack, you can cut them in parts to separate as needed. I cut it in half so when I am using on half the other is freezing and I always have a frozen one to switch to when needed. They stay frozen for about 10-12 hours in an insulated lunch bag

I like this Medium size more than the large one that I bought. It fits better in my igloo cooler better.

This is such a good buy. I have a bunch of these in my freezer I pop them in a freezer tote when I. Shop and they keep my refrigerated items cold until I can get home.
