Ok, I should've been more specific: use an archival baggie.  A plastic
pill bottle will out-gas and eventually become brittle and leave a little
mess (and drop the screws).  Granted, this will take a fairly significant
period of time.  An archival storage pouch would be better, perhaps one
made of cloth.

And might in fact etch the metal.
