I needed some new ice packs for my 4 +5 year old's boo-boo's. When I stumbled upon this 2pk of Hot + Cold packs, I was excited bc who doesn't need the best of both worlds?! They came on time, packaged nicely + seem to be of high quality! I'm excited to see how many years these last. I highly recommend this 2 pack, as you can use them either hot or cold, over and over!
