Ice Crystal Box Reusable Ice Water Cooling Container Outdoor Home Gel Cold Storage&Preservation Bag

•Coarse Particles: The dry ice crystal granules inside the ice crystal box are coarse, offering excellent expandability and a long refrigeration duration.

•After Receiving: Upon receiving the product, simply add water. The ice crystal granules will swell upon contact with water and, once expanded, need to be frozen for approximately 2-4 hours. They can then be removed and used in a lunch box or similar containers.

•Please Note: During the process of absorbing water and freezing, ice crystals expand. Therefore, when adding water, it is important not to fill the container to the brim, leaving adequate space for the ice crystals to expand.

•Safe to Use: Any overflow of ice crystal liquid due to swelling is non-toxic. After a simple cleanup, it does not affect the product's usability.
