Long leather wallet with Louis Vuitton's Monogram design. - Brand: Louis Vuitton - Design: Monogram - Material: Leather - Style: Long wallet Thank you for viewing. Since this was purchased after 2021, the serial number has been discontinued, and an embedded IC chip is installed. You should be able to confirm something like a serial number by holding your phone over the wallet using an app like an NFC reader. I purchased this from an authorized retailer, so I don't think it's a fake, but I will accept returns if it is, in the unlikely event that it is a counterfeit.
