YSL Yves Saint Laurent Leather Clutch Bag Brown

AUTHENTICITY GUARANTEED

Lost Designer guarantees authenticity of the designer items we sell using the services of two authentication partners.

Authentication uses a combination of artificial intelligence and microscopy to objectively assess the authenticity of an item.

Cutting-edge technology produces 260x magnified surface photographs of the items it scans. The precision of the rich visual data combined with machine learning and analysis identifies and guarantees authenticity.

Every bag and wallet we sell that is supported by Entrupy is accompanied by Entrupy’s Certificate of Authenticity. The most trustworthy testament to true value, Entrupy's authentication accuracy exceeds 99.1%.

*While it is highly unlikely that an inauthentic item will be misidentified as authentic, in the case you suspect an item you purchase from Lost Designer may not be authentic, contact us for a review or a full refund within 7 days of purchase.
