Hi-I just purchased a patent flap from Malleries. Maybe I'm being a little neurotic or I'm just out of practice buying pre-loved, but now that it's on it's way to me, I'm worried it's fake. I just realized that there wasn't a pic of the back of the bag & I'm curious if all flaps have the pocket on the back?I've looked on eBay, etc...for comparison pix & I know that just bc there wasn't a pic doesn't mean there isn't one. I also know that there are a lot of different incarnations of the flap & was curious what you all knew about it or your experience. Thanks in advance!
