Cool Coolers by Fit & Fresh 4 Pack XL Slim Ice Packs, Quick Freeze Space Saving Reusable Ice Packs for Lunch Boxes or Coolers, Blue, 239ICE, 4 count (Pack of 1)

Bought as a gift for my husband for Father’s Day in tandem with a lunchbox. I love the tall size and thin sides. Works great, fits nicely, easy to use and clean, lasting most of the day. I suggest laying them flat to freeze, otherwise it can cause them to expand sideways and warp the sides a bit making the ice packs solidify unevenly. A couple started to leak a few days in but stopped, then leaked a bit more later on. I did call and get a replacement, and the new set seems to be just fine. Thankfully these are a great value for the price, but if you need to buy a replacement they’re relatively cheap. 9/10 would recommend and buy again.

Had these for about a year now and they're still good. They fit great in my particular lunch bag/cooler. I place one on all 4 sides and they fit perfect and make a more rigid wall. Keeps my lunch cold all day indoors, but I also use them in the same lunch bag and throw a 6 pack in it for when I'm hanging out on the patio having a few beers. I live in AZ and while its not the dead of summer yet, at around 90 to100° degrees they last a good 4 to 5 hours at least. Usually starts to cool down by the time I'm done and while they've become liquid again they still keep the drinks cold and thats all that matters. We'll see how they hold up in the extreme heat but they're great for the price.

They keep cold a long time. I'm on the go a lot and need to keep my babies mill cold, these fit perfectly into a lunch bag, super easy to use and work great.

Slim so it fits anywhere in the freezer. Easy to use. Color is fine doesn’t seem to leak or anything. Quality is fine, and it works as it should!

These reusable ice blocks are a total game-changer for my cooler setup! I used them for a weekend camping trip, and they kept everything cold for hours—way longer than I expected. No soggy food or water pooling at the bottom like with regular ice, which was a huge plus.They're super convenient to freeze, and the slim, compact design fits perfectly around drinks and food containers without taking up too much space. I love that they’re reusable—it saves money and cuts down on waste.The plastic exterior feels durable and doesn’t crack or leak, even after multiple uses. Whether it’s for road trips, picnics, or just keeping lunch cold at work, these ice blocks get the job done.Highly recommend for anyone who needs a reliable and clean way to keep things cold on the go!

seems thin, good ice packs i just throw them in freezer and use them. no leaks so far!using them with thicker ice packs too will leave them frozen for longer.

I haven’t run into any issues, they are a great thin ice pack! Which also helps with space since it’s not chunky. These are usually my go-to for lunch boxes but they could be more versatile- I would use all of them at once for almost a full day of keeping things cool. I’ve recommended it to friends and family and they don’t have any regrets either!

In a small lunch insulated cloth bag one ice brick lasts almost a school day. By the time it's home it's all liquid and warm, but was cool to the touch at lunch.
