This is overkill, but for long-term storage I'll put a fresh small box of primers (in other words, not the Federals I use for a lot of loading) into one of those foodsaver shrink bags and seal it. That sucks the air out and will keep the box fresh even if there's a water leak. No need to worry about Florida humidity, etc. Someday I'll get more gung-ho and find the right size dessicant packs to throw in there with them. The only downside to this is it makes 'em more difficult to stack, but you can still cram the boxes into ammo cans.

Those foodsavers are great for keeping almost anything dry, including your spare currency.
