PinnacleIce Blocks for Cooler Set of 2 – Multipurpose Ice Packs for Coolers Long Lasting Reusable Refreezable –No Leak Lunch Box Ice Pack – Non BPA Food Safe Freezer Packs for Coolers

I have a variety of sizes for different uses and these are great for keeping stuff nice and actually cold in an insulated small bag even in SE Texas all day in the summer. Highly recommend. They can also augment a bigger bag with the large ones as a base and these spread thru to keep items from warming up just from being further away in the bag than is ideal, especially if someone doesn't seal it all the way.

These work great. They're nice and slim and don't take-up as much room as the old ones I had.

Served its purpose. I used these in my cold therapy machine instead of using ice all of the time.

Love these for my daughters lunch box. I usually wait until they’re in bed to fix their lunch for the next day, and the ice pack is still very cold at 9-10pm so about 13-14 hours out of the freezer. Seem very durable as well. Glad I purchased these.

I have a disability with heat over 75 degrees where I become dizzy and need to stay cool inside in places where people like the "warm".

works fine. No leak.

Had them less than a year and already one has a hole. They both swell severely when frozen. Manufacturer claimed they would send replacement, but they never followed through. FAIL!

Works well for what I wanted
