Title
Dry & Store Hearing Aid Conditioning System
Description
Inside the gold foil wrapper, the Dry-Brik itself is covered tightly with clear plastic that has very very tiny perforations. (You can see the holes if you hold the Dry-Brik up to the light at different angles.) The holes are large enough to allow moisture molecules to pass through, but they're small enough to not let the silica gel out. Surprisingly, the more moisture that the Dry-Brik adsorbs, the *dustier* it becomes. That's why it's important to leave the clear plastic intact.
There's a copper strip on the end of the Dry-Brik. It's necessary only if you have the Professional model. If you have the Global model, the copper strip isn't needed. However, if you've removed the copper strip, then please ensure that the cellophane is not ripped open where you removed the strip. When you open your next Dry-Brik wrapper, just leave the copper strip in place. It won't bother anything with the Global.
