AUTHENTICATION SERCIVE

%100 Original, Guaranteed — 
because you deserve it

At Lost Designer, we know trust is everything. Shopping for pre-loved luxury should feel exciting, not stressful. Unfortunately, the reselling world can sometimes feel overwhelming, with counterfeit handbags, purses, and more everywhere! That’s why we’ve made authenticity our number one priority.

We stand by every single item we sell. Our team of experts is trained to spot the tiniest details, ensuring each piece is 100% original. And to prove just how confident we are, we offer a Lifetime Return Policy. If you ever find an item we sold isn’t authentic (which, let’s be real, won’t happen), we’ll take it back, no questions asked. 

Verified Authenticity

We’ve teamed up with Entrupy, a global leader in authentication technology. Entrupy is so confident in their process that they back it up with a money-back guarantee. Each item authenticated by Entrupy comes with a digital Certificate of Authenticity. 

Here’s how it works: Entrupy uses uses advanced AI and machine learning to power a meticulous microscopic camera that takes highly detailed images of a bag’s surface — we’re talking 260x magnified! These images are then cross-referenced against a massive database of millions of real images. The result? Worry-free shopping and 100% original items from your favorite designer brands.
