What is the authentication process? 03 May 2023 11:57 Updated Once you make a purchase, the seller will send the item to our warehouse. Here, our dedicated team of experts check every detail to ensure the item is guaranteed authentic, unused and in its original packaging. If the item fails authentication, it’ll be rejected and sent back to the seller and the buyer will be issued a full refund. If it passes, the item will be sent straight on to the buyer.
