Hypothetically speaking, lets suppose someone were to be thinking of buying a 7 year supply of a particular blade, and 3 years worth of some other blade as well. Should this person be concerned about storage for such a long period of time as it will take to use up his supply of blades? Is chucking them in the closet next to the bathtub for an entire decade OK, or should they be kept in a hallway closet where the air is dryer? Would this hypothetical blade hoarder be way over the top if he procured a surplus air-tight ammo can to store them in, along with a few dessicant packs?
