Cello on or off?

I prefer smoking my cigars with the cellophane wrapper on. Much more appeasing flavor.

Don't worry about calibrating your hygrometer. As long as it looks cool and you have one, those things are pretty much for decoration.

You need to do that when they turn yellow from age. All the flavor is in the cello then.

Think of it as a cigar condom. It can help protect your cigar from beetle infestation. It also keeps your cigar clean, Bill can tell you that.
So what it really comes down to is "What kind of social life you lead".
