In no way am I saying I don't believe you. I have had even non maduro cigars have color come off of them. I just didn't notice it on the four I smoked and now you have peak my interest LOL.
I had a Gran Habano last Fri (Corojo #5 lancero) and boy was I surprised when that thing turned my fingers brown! I would not expect a corojo to be dyed. Is it time for a revolution to stop makers from dying their cigars?!
