You are smart to beware of fake Celine Pink Fluo Bags. I have helped with six PayPal cases in the last two weeks and they were all fake Celine Fluo Pink bags in the nano, Micro, Mini, and even shoulder size. The pics look good, so it is really tricky. . . .the are only two ways I can distinguish these from real ones by pics alone--I am not saying what they are b/c I don't want to help counterfeiters, my point being it is really hard to tell.
I have a friend who has an authentic Celine Pink Fluo Micro, but because of all the counterfeits she is having trouble selling it. It really makes me sick to see these people list over and over again--see the thread on "A place for the fakes" before considering buying one off eBay/internet.
