Authentic bags do come with a black tag inside the zippered pocket and consist of letters and numbers. Fake bags have been duplicating this too, so it's hard to tell unless you can see a difference in the font.gracefeng said:Hello! I have been seeing some MJ bags on ebay which have a black tag in the inner zippered pocket with a code on it. Does this make the bags fake? The other details are consistent with real bags? I have had people tell me that the tags are in newer real bags such as the Selma and the Carmen. Also, can suede lined bags have an inner zippered pocket that is not suede but lined in canvas? Thank you so much and any help would be appreciated!!!!
