I've got one of those Tilla Foodsavers too ... and have pondered the same question. I know that it creates a vacuum, thus leaving no air for mold or bacteria to grow in. That's why you use it on veggies (even salads) and any other food products, for that matter, and it will prolong the shelf life for quite awhile. It does not take out moisture, only freeze drying will do that. It will not crush your 'gars either, just tightly conform around them. If you put them in in a mason jar (if you have the jar attachment), the air will be removed and your cigars will be unharmed if they are firm ones to begin with. Have you seen what happens to marshmallows? They blow up like balloons ... if you try to seal them 'container in bag', you are not really taking out all the air. Go ahead, and experiment on some 'dog rockets' and see what happens. If you would like, I'll send you a box of Anillo de Oro Tamboril's (minus two)... nasty buggers they turned out to be! I've thought the Foodsaver idea would be great for sending 'care Packages' to friends through the mail. No matter how long the trip, or how hot or cold, they would arrive exactly how I sent them ...
