Mike, the numbers on the cigars is used along with missing put/take list to identify what the cigar is.
I don't know who used the single cigar bags.
The Hoyo band is similar to the band used by the Cuban Hoyos for a series of figurado-shaped cigars that Hoyo came out with a few years ago. I just checked my Perelman's Cyclopedia and could not find them listed, so I am assuming they are not being made anymore. Does anyone know if they are still being made or not?
