Dynamic Gear Reusable Ice Pack Blocks, 6 Pack | Slim, Lightweight, Portable Freezer Block | Cooler Ice Packs for Lunch Box/Bag, Cool Bag, Fishing Box, Picnic Bags | Travel, Sport, Camping Gear Coolers

Great value, easy to use. I use these in my kids school pack ups and for days out with the family. Handy to have a few for when they don’t make it home each day!

These are great for our lunchboxes, very well made, freeze quickly and last a long time when I use.

I got fed up with warm sandwhiches after being left in my work van until I had time to eat. So I thought I’d give these ago with a lunch bag. They have proven very reliable, keeping my sandwich and drinks cold and fresh. Definitely would purchase again.

Great item to keep lunchboxes cold. Nice slim design so as not to take up too much space

Great ice packs and what a great price. Quality is very good for the price, they are just the right size and shape for my needs.

We use these in our little cooler. Great size and fits most kids' lunch packs. They stay cold for quite a long time too, but I wouldn't recommend beyond 8 hours for perishables.

Worked really well at keeping my drinks and lunch cool in my cool bag on a 5 hour train journey. They stay cold and frozen for a long time.

Compared to a simple gel block that you can buy from the big discounters they last half the time. I ordinarily purchased these as their selling point was slim and smaller profile, however this comes at the cost of them not staying cold as long as a traditional block. Are they slim and good for small lunch box’s? Absolutely, do they last to midday? Not really. I have to use two or more which kind of defeats the object.
