Blue Ice Packs for Coolers, Shipping and Lunch Box, Slim Size Long-Lasting Reusable Ice Pack, 4" x 4" Cold Gel Freezer Packs for Camping, Beach, Fishing, Shipping Food

These worked perfect. I had to ship some cheese to my daughter. I used insulated packing box and these to keep the cheese cold. I did ship in the winter from Delaware to Florida and overnight shipping. When my daughter received the package the cheese was still cold. These didn’t leave and they are easy to use.

At first I thought these were supposed to be freezer gel packs. When they came they were very small and had some kind of powder in them. I was disappointed and gave a bad review. After looking further into the product instructions, I found out I made a mistake. After you soak these in water l, they expand and freeze well. I left them in my lunch bag I take to work over the weekend in my car. They thawed, but did not leak. They're actually pretty cool. I stopped my return. My apologies! Great product!

I used them to ship a cake. A lot come in the package so that is nice but it did not keep my cake cool for 48 hours. Could be to much to ask as it was just in a box though. Otherwise great product

Worked great for overnight travel. Lasts about 30-36 hrs vs 48 hrs.

These ice packs are small, relatively light weight, easy to slip into a small insulated container to keep food chilled. I used some to keep cookies frozen. The packs still had solid ice in them after 12 hours of traveling. I am happy with them!

After 12 hours ice pack was warm

Did the water thing, froze for 24 hours. Will only keep stuff cold for 6-7 hours.

It is good
