Our buying team carefully reviews all items in person. They are trained to look for hallmarks of authenticity, including materials, construction quality, and hardware. They review the interior and exterior of each item carefully before sending it for further authentication. Select items are sent to our third-party authentication partners, Entrupy or Real Authentication. Entrupy uses a microscopic camera and advanced AI technology to compare handbags to a massive database of known authentic and counterfeit items. Items deemed to be inauthentic are returned to the supplier immediately or donated after 2 weeks of being unclaimed. Please note: Suppliers will be charged an authentication fee.
