However with the regular plastic BB's no special care is really required.

Only snipers really do that and it's not like they fire off a terribly high number of BB's off in a day anyways.
All BB Bastard BIO bb packs come with a moisture pack in it. As long as you keep the bag sealed with this pack in it, your bb's will not break down.
