The Zip-loc bag I had wasn't really Zip-loc brand. I had a cloth and leather bag with a zipper, provided by the Audi's office when I got my hearing aids. No moisture at all with the aids as I would dry and clean them before putting into the bag. Had lint free cloths for that. My HA's did not come in a hard-shell box, only this little zipper bag. Don't have the HA's anymore as they met an untimely demise and now, they would be no good. My ear infections were mostly "swimmer's ear" from the shower and I still get drops even 5 years later.
