Don't listen to Scotty, he has no idea what he's talking about. He's never aged cigars therefore has no first hand experience to offer you other than a link to a bullshit website that is full of wrong information. Scotty is famous for coming across like he knows what he's talking about when in fact he does not.

Also, the site that Scotty gave you as a reference has a lot of information that many experienced people in the cigar world completely disagree with.

Leave the cello ON. It protects your cigars from damage. Cello on or off has NO EFFECT on how your cigars BREATHE (that's "breathe" not breath ). Cigars don't "breathe" they are NOT alive. Since the cello on the cigars is not 100% airtight, your cigars will retain and/or lose moisture whether you leave the cello on or not. The cello is placed on the cigars by the manufacturers for PROTECTION plain and simple.
