INSTRUCTIONS FOR USE.

The more tightly enclosed moisture proof you can make the storage enclosure the better. Otherwise, your silica gel will absorb moisture from outside of your storage enclosure becoming saturated and requiring reactivation frequently. It's worth it to do your best to make your storage enclosure as moisture proof as possible.

Just Remove the protective pouch in which your Hydro absorbent unit is packaged. Position your Hydro absorbent unit on an exposed surface anywhere within the enclosed area to be protected. Examine the indicator from time to time to see if reactivation is required.
