matters needing attention
When soaking, the lower the temperature of the water and the cleaner the water quality, the better the use effect (using chilled pure water for soaking is the best).
The soaking time of the inner bag should not be too long, as excessive water absorption can cause the absorbent material to expand excessively. The inner bag is too hard to fit an insulin injection pen.
If this situation occurs, please place the cooling bag in a well ventilated area until the injection pen or insulin you need can be placed (the duration depends on the specific situation).
Do not place the cooling bag in an airtight container. The working principle of the cooling bag is to use efficient water evaporation for cooling. Please ensure that the cooling bag is in contact with air and can be placed in clothes and bags made of breathable materials.
Save:
When not in use, please place the inner bag in a well ventilated area and let it dry naturally until the refrigerant returns to its crystalline form. Regularly shake the inner bag to separate the lens. After fully drying, the insulin cooling bag can be stored in a dry and ventilated environment.
How to clean:
The outer bag can be cleaned with gentle detergent and water at around 25 ℃. When cleaning the inner bag, please use a small brush dipped in a little soapy water to lightly brush its surface, then rinse with water and place it in a cool place to dry or wipe dry (do not use a washing machine to clean).
How to extend service life:
We suggest that you soak the inner bag in clean water (deionized water is best) to avoid using sewage or seawater. Avoid direct sunlight when not in use.

The above items are only for guidance and reference. The effectiveness of cooling bags may vary depending on the climate and environment around the world. As the number of uses increases, the water absorption time of the refrigerant in the inner bag will also increase, but as long as it can expand into a gel, it will effectively play its role. When the refrigeration material completely loses its expansion function, you need to replace a cooling bag.
