Poshmark claims they don't allow counterfeit products sold on the site but I have a bag which is obviously a cheap plastic knock off and they have ruled that it's genuine. I have since seen exactly the same bag in different colors embossed with spades and MK being sold as authentic Kate Spade and Michael Kors. The site allows this. It's plastic, the C does not line up. The straps are flimsy and the dust bag is white.
