I am so mad, I could spit fire!! I just sold my friend's black coffer on eBay and finally got a response from the buyer. She said that she took her laptop to the "Prada Store" and that they said that the coffer should have a riri zipper on it, not a coffer. So she said that she does not want the bag now because she "does not believe it to be authentic"! I can't believe the ignorance of some people. I have called Prada stores before and they never carry Miu Miu in my experience. Anyway, could any of you Coffer girls please take a look at the zippers on your coffers and tell me if any of them have Riri zippers or not. All of mine have Lampo. ALL 5 OF THEM!! Your help would be greatly appreciated!
