Chicago Consignment has partnered with Entrupy.com (www.entrupy.com) for product authentication. Entrupy’s artificial intelligence device is used to scientifically authenticate Louis Vuitton, Hermes, CHANEL, Gucci and more. Any brands not supported by Entrupy are then authenticated by other respected third party services, i.e. Bababebi, Authenticate First and others. We authenticate every item using a respected third party service before listing it for sale. We guarantee authenticity or will provide a full refund.
