I can speak as a retailer....... Cello helps prevent damage for those folks who rumage through each stick. These are the ones that feel inclined to sniff - snort, -squeeze and roll their hands all over the cigar. They know who they are. Why they feel the need to want to do this????? 99.99% have no clue about premium tobacco. Anyway, I call cello a sneeze gaurd. Personally I would love to see every cigar come naked (no cello). Just a personal preference.
