They get much better with age trust me, my main reasons for keeping cello on is for protection and IMO I think it keeps cigars fresher and i do think it helps cigars age better in the same way some cigars are wet packed. Cigars are wet packed to improve the flavor over time. Pete Johnson recommends that the cigars he wet packs sit for 2-3 years. After smoking a few DD's I can say I get why he does it.
