MR.ICE Dry Ice for Shipping Frozen Food 15 Packs - Cold Packs for Shipping - Dry Ice for Drinks Coolers Dry Ice Packs - Freezer Packs for Lunch Box - Long Lasting Ice Packs, 6.9" x 4.7"

They kept cold for a great length of time. Next time I use them, I would probably not fill them up with water as much because it wasn’t really comfortable trying to fit them in when they were about the size of a pop can. Would probably try to get them flatter next time. But overall effective. Would get them again.

Fine after they’re soaked, frozen and thawed once, they swell up perfectly. Well worth the price. Use them in my swamp cooler and they fit exactly in the space they’re needed.

Shipping was prompt, the product was well packaged, and it performs as advertised. Overall, a good experience and a quality purchase

I was making a 10 hour trip with my granddaughters' birthday cakes and cupcakes and needed to keep everything cool. Ice packs plumped in under 3 minutes in water and froze overnight. Packs partly defrosted in the coolers on the trip but kept everything cold. Great buy! Dont let them touch as they freeze or they will stick together. My only complaint is they don't dry up to put away. I left one sitting out for three days because it popped opened and it never dried up.

What I liked was they enabled me to send homemade candies to my grandkids. What I didn’t like, I followed directions included, and two of the four packs burst open once frozen. I had to discard them.
