here is what I would do:
you must mean silca gel packets....
yes- and in an airtight container- pelican case - of similar food storage device with rubber gasket
or if none of those are available- a freezer ziplock
yes all with silca gel packets- which you can dry out in your oven - set at warm (lowest temp) or if its a gas oven with a pilot light place them in it while off over night- this will expel any previously accumulated moisture and ensure that are ready to reabsorb moisture again.
I always store my mics in a pelican case with silca gel - even between gigs, overnight or what ever.
also I always remove my wind screens for storage - to ensure full fluffiness!
