Hmmmm........I haven't had a problem with the original Black Perles as far as any coloration from the wrapper coming off, but haven't tried the newer ones. To me it is a fine smoke and this would be a disturbing development if it holds across the board. I have smoked some cigars that turn the lips dark, almost like licorice candy (that you don't know about until you look in a mirror after smoking them) and don't like that effect.
