8-Piece Ice Packs, Portable Long-Lasting Freezer Blocks, Ice Packs to Keep Ice Cool in Refrigerators, Air Conditioners, Fans, and Cooler Accessories

Effective Cold Insulation: Our freezer packs contain dry ice crystal particles that provide exceptional cold storage. With their coarse particles and strong expansion capabilities, these packs offer powerful cooling performance. They can be used in conjunction with air conditioning fans to enhance the freezing of cold air, creating a more comfortable and refreshing environment. These freezer packs require the addition of water to activate. These freezing blocks are designed to provide long-lasting cooling effects. Once water is added, the ice crystal particles expand, so it is important to leave enough room for expansion. After expansion, simply place the packs in the refrigerator for approximately 2 to 4 hours, and they will be ready to use in your lunch bags or coolers.
