Igloo Maxcold Ice Blocks, Long Lasting Cold Freezer Ice Packs

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!

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.

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.

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

Got this for a bigger cooler and it works wonders. Lasts a very long time but the only downside is that it bubbled in the center, so it's no longer flat on both sides. Otherwise 5 stars.

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.

This little thing was about a dollar when I purchased. Works great in lunchboxes although or when you're transporting them during a road trip. I usually add one on top and one on bottom to make sure stuff stays cold. Of course, it depends on how well the box/pouch you are using. One of the better things is that they can be stacked meaning less space taken up when storing or freezing them in the freezer.

These do a great job at keeping food in the cooler cold. My husband uses them to keep his salads cold while at work and it does the job!
