Below Zero Deluxe Stainless Steel Cooling Pack - for Those Who Need The Best - Filled Gel Patent Pending - Longest Lasting Cool Pack

metal ice packs holds the cold for hours - it was still slightly frozen after all day in my sandwich cool bag. Watch out your fingers don't get stuck on the packs when handling/taking out of freezer.

I try to buy things that are non porous and will last the rest of my life. Pretty sure these will be with me til the end 😆 They stay extra cold for extra long, just wish they had a bigger size option.

These ice packs are amazing. Used them on a cross country trip. They even worked in crappy hotel room freezers. When frozen at home they lasted two days and were still cold when I put them in the freezer. Would highly recommend !

I take these every day in my lunch box and they are SUPERB!!! They stay cold, do not leak, and allow for extended periods of time keeping my food cold which is necessary as I work long shifts at a hospital! I have also run these under water to clean them, and they clean up really well. I even put them back in the freezer after rinsing and did not dry them and they did not stick to each other much to my surprise! They require very little time to freeze and are slim enough for me to fit all of my food in containers into my lunchbox! They are stainless steel and very appealing while their durability and longevity prove to be lasting.... only time will tell!

These are the best ice packs available! They stay cold without fail.. Extremely cold temperatures! The most notable feature is that they retain their coldness for hours, lasting significantly longer than standard ice packs.
