KomaxReusable Gel Ice Packs for Lunch Bags, Set of 6, Slim Design, 8 Hour Cooling, BPA-Free, Food-Safe

These lasted over a year before having to repurchase due to punctures causing the jelly inside to leak in the lunch box. That to me seems like they are made well. These keep items in the lunch box cold for more than 8 hours even during the summer months. They last much less if the lunch box is left in a hot car - maybe only a few hours.

I’m a commercial electrician, a some days it’s an 8 hr day, or 10, maybe 12 hrs. These are the absolute BEST ice packs I’ve ever had!! They keep all your drinks a food cold in your cooler.Like I said in the title, if you’re a blue collar fella or gal, this is ALL you need. My cooler has been sitting in the sun in my passenger seat, a the drinks are as cold or colder than when you get it out of you’re fridge at home.Shout out to Komax for making such an awesome product. I HIGHLY recommend this to all my brothers and sisters in the trade. Definitely worth the $$, an they come in quick.

Wow!! These things are amazing!! They stay frozen for several hours, not just 3 or 4. They are thin and fit underneath and on top of any food in a lunch bag.By the way somebody rated these low because they were a “block of ice.” Yes they do turn into a thin block of ice. However, that’s what makes them perfect! I’ve used bags where the gel is more flexible. Those do not stay cold or frozen for long. These do.

Some pouches took a lot longer to freeze than others. Aside from that I love them and honestly that wasn't a big deal! They work! They allow me to keep my lunch away from community storage and I don't worry about it spoiling.Adding some information. While these were great to begin with they weren't very durable. After several months of use they began to get cracked and leak. I've been careful to lay them flat and avoid folding the edges when freezing. They were great but didn't last. I dropped a star for that purpose.

We love how thin, light, and long lasting these ice packs are. Stay frozen for a while!

Works Great in my lunch pail .Cold 🥶

I use these all the time. The sad thing is, I’m losing them because other people borrow them and I leave them placesThey fit perfectly in my lunch bag and in the bag I use for my Golf snacks they stay frozen for 3 to 4 hours, which is plenty

Update: ill book to have torn. And they have torn while putting a water bottle in the cooler. Normal activity. I wouldn’t buy these they just don’t stand up to any kind of use.I’ve been using these for about a week and so far two of them have torn. They’re just not very strong. They’re the perfect size for my sports cooler. They keep things colder than most other packs. Just disappointed that they don’t stand up to the use.
