WORLD-BIO Dry Ice for Shipping Frozen Food & Travel, Long Lasting Cold Packs for Cooler 96 Packs 4.7" x 3.3", Small Freezer Packs for Shipping, Bulk Reusable Dry Ice Packs Cool Pack for Shipping

Excelent product

Great products.

Good product, it maintains the temperature for 12-24 hours if hermetic conditions

The packets are very small and do not last long.

They work great for shipping!

Bio Ice bags Look Like they will work well, but don't stay frozen long. These are flat packets that arrive and you "inflate" them by soaking them in water -which they absorb--then you take those packets and freeze them. The problem is, these don't last long - we tried to use them to mail a package of meat from Illinois to North Carolina and all the packets leaked water after they thawed in transit. We sealed them in a large bag around the meat to keep it cold within an insulated box- and they were a giant pool of warm water by the time they arrived. Horrible product.

These are super convenient and easy to use! They help keep sea moss that i ship cold for 1-5 days!

So cheap and they work for my office to ship cold items
