Product description

After opening the package, why are there only four thin sheets inside?

Thanks for asking! After absorbing water for about 5 minutes, the sheets will expand and turn into ice packs ready for use.

Does it need to be soaked in water before each use?

No need to soak it every time. Our product features dry white resin pellets inside and waterproof fabric outside. Once water is absorbed, it locks it in to prevent leakage.

Can ice packs be frozen or heated?

It is suitable for both cold and hot use. It can be placed in the freezer for freezing, and can also be heated in a microwave or hot water.
