1. When using it for the first time, open the sealing of the ice bag's water inlet, and fill it with clean water (not exceeding 2/3). If you fill less, you can add more.

2. Exhale the air from the ice bag, and gently squeeze the seal to close it.

3. After a few seconds, the material in the ice pack will react with the water to form a gel-like consistency. At this point, the material in the ice pack will not leak out through the filling port, but please do not apply pressure or come into contact with sharp objects.

4. Place the prepared ice packs in the freezer compartment of the refrigerator to freeze into a solid block.

5. The cooling effect can last for about 10-12 hours. After complete thawing, the contents will return to a gel-like state. At this point, it can be placed back into the freezer for freezing, ready for use the next day. The number of times it can be frozen and thawed is over 1000 times. The shelf life of unfilled containers is 3 years, and the shelf life of filled containers is 1-2 years.
