COOLER SHOCK Cooling Packs, Large Size, Set of 2

COOLER SHOCK Ice Packs, Large Size, 2-Pack (Includes 2 Silicone Corks) COOLER SHOCK Ice Packs, Large Size, 2-Pack (Includes 2 Silicone Corks) * COOLER SHOCK ice packs are designed to maintain a temperature of -7.8°C for extended periods. * Both ice and ice packs, including COOLER SHOCK, start at the freezer temperature (0 to -12.2°C) and their temperature rises once removed from the freezer. * Ice quickly heats up, reaching 0°C and eventually melting, but Cooler Shock is designed to maintain -7.8°C, thus maintaining the cooling effect inside the cooler box for a longer period. * Compared to ice, COOLER SHOCK requires less quantity to achieve the same cooling effect, reducing the weight of the cooler box and improving space efficiency.
