Is it safe to store my blades in a bathroom closet or should I move them to another room where there's no moisture? My Voskhods are wrapped in cellophane but the Astras and some others are plastic free. Is the moisture in the bathroom (steam in particular) enough to degrade my unopened blades? Some people suggest it's not enough moisture to penetrate the packaging and affect the metal but I still worry about all those blades going bad. Am I being paranoid? Any input is greatly appreciated. Thanks!
