Ice Packs for Coolers - 600ml Cooling Elements for Coolers and Insulated Bags - Cold Packs for Home or Leisure

This ice crystal container contains dry ice crystal particles with a coarse texture, offering good expansion and powerful cold storage. Upon receiving the product, you will need to add water yourself. After adding water, the ice crystal particles will expand and, once expanded, freeze in the refrigerator for approximately 2 to 4 hours. They can then be removed and used in a lunch bag or similar container. The ice crystals will expand during water absorption and freezing, so do not add more water while adding water; leave some space in the container. If any liquid overflows during the expansion process, it is non-toxic and can be used after cleaning. It offers extra-long cold storage and can be used repeatedly.
