Dry Cigars

Cello on or off doesn't really make a difference, as the cello isn't airtight. The other brothers are right that you should rehumidify them, but I'd strongly suggest you do it in stages...a week or so at 60, then 65, then your ideal humidity for as long as you like (like Matt said, time is your friend). Keep an eye out for wrapper damage (especially at the foot); it's a sign that you're bringing them up too fast.
