Shipping Ice Packs Reusable Small Dry Ice Pack Sheets 48 Packs, Ice Pack for Shipping Frozen Food Keep Food Fresh Beverage Cold, Frozen Gel Ice Packs for Coolers 3.5 oz Capacity, 4.7" x 3.3"

These work great for shipping. They are the perfect size for shipping in the winter and I only need to use one to keep the product slightly cool during Shipping. They are easy to fill up (takes 5 minutes to soak up the water) and feeezes overnight. This is the second set I have bought and I love them. They are a great price too!

Worked perfectly! Perfect size, Stayed frozen for many hours. Did not leak and we were able to reuse them! Very durable

Worked very well when used.

It’s so helpful, I use it for mylunch bag and every time I need to keep anything cool on long drive, use it to ship the cake in the cooler box last long for 3 days. But it’s broke after reused couple times, and so annoying that stuff sticking to my food and that is second pack in 48 packs broke. Let’s see

Amazing

These are SMALL! I was surprised to say the least! Maybe I didn’t read the description well, so be sure to read. These measure almost 4 inches by 2 inches. The ones we used did not stay frozen for the day, but they kept the food cool enough. Will work for grocery shopping in Texas, but not my “go to” for long trips. Also, several split while they were freezing and had to be thrown away.

I liked that they are small size it made it easier to pack around meat. We were take two 5-6 pound roast from New Jersey to San Antonio, Texas and I Googled dry ice. And these freeze packs came up. I read reviews and decided to try. They worked great! I must say they really did not come with directions I read in reviews that you hydrate them in water. Someone warned not to over hydrate but you don't know what over hydrate is. I also have to say to only do a few a time because you want to keep packs straight with no wrinkles.You get alot for the money and we only used about 20.

Bought these to take on an international flight to keep food cold. I tested these at home. The average cabin temperature on international flights is 71 to 74 degrees F (22-24 C). Our home runs at 69-71 degrees F. in my test, I added two frozen items and 9 frozen packs. All (including the little frozen packs were thawed and warm. I checked them at 6, 12, and 22 hours. At 6 hours, the frozen items were beginning to thaw. At 12 they were thawed. At 22, they were warm. Epic fail.
