I typically smoke cigars at 61% and long term age at 58%.... IMO less moisture and more flavor. Pretty standard levels for what the English have done through the years. 65% is on the high side, 70% you are smoking sponges....
Cubans in my experience are best smoked drier, I keep one of my humidors at 62% for just Havanas. I'd say no fridge or freezers. A slightly moist pillow/towel with distilled water will do just fine if you can't get to a tobacco store for a Humidified Bag that's been made in the past 5-10 years by Fuente and a few others. Cigars are more durable then people may think, 1-2 weeks in a sealed bag should be fine.
Thanks for the tips. The cigars are in a little paper-lined box, which I put into the bag with the damp towel. In retrospect I guess I should have double-bagged it as recommended in this thread.
Mega - in the future, using the double bag technique will keep your cigars fresh. If you anticipate longer term storage, mixing 50/50 distilled water and propylene glycol will provide a stable environment plus avoid the issues of the mold spores showing up.
On a related note, on occasion, I enjoy pipe smoking also, especially as fall/winter approaches. I neglected my pipe tobacco for a number of months as I wasn't smoking it and the tobacco dried out (as in crunchy). I dropped all the baggies of tobacco into a large gallon size zip lock bag and dropped in a small piece of florist foam wet down with the above mentioned 50/50 solution. I checked it over time and after about 4 months, each bag had reclaimed its prior moist nature and smokes just great.
