you're going to get some drying regardless of what you do, just as a new pack of commercial cigs starts to dry as soon as you open it. And their packaging ain't that great, buy a pack, let sit for a few months, then open to dry cigs.
I recommend a tightly-sealed plastic container, will work for a few weeks if full of cigs (less air space). Zip-Loc
For my new rolled cigs, and stored shredded baccy, in sealed containers, I use the following:
cut a 3 or 4 inch square piece of aluminum foil,
take a piece of paper towel, folded several times, but smaller than foil piece,
wet the paper towel & squeeze out excess water,
set foil over the baccy in your container, with the wet paper on top, then seal the container.
This will create a moist environment inside your container, keeping your baccy in case.
Never let the moist paper touch the cigs or baccy, this may lead to mold, as will an excessively wet wet paper towel, or too large of wet paper towel piece for the amount of stored cigs/baccy.
Check the paper towel every couple weeks, re-moisten as necessary.
This works for me, your mileage may vary !
