Purchased from a domestic authorized retailer. It is definitely authentic, so the "Authenticity Guarantee" service is available! Although it has been used only a few times, there are some coin marks. I plan to sell it to a pawn shop if it doesn't sell, so it will be listed for a short period. I cannot offer a significant discount. Please purchase if you understand that this is a used item stored at home by a private seller. The serial number is an IC chip type. Returns are not accepted to prevent swapping. (Please use the "Authenticity Guarantee" service if you are concerned) There is no box or dust bag. Instant purchase is OK. Prada wallet Prada mini wallet Prada coin purse Prada triangle plate
