Authentication with Entrupy | St Luxe

Got Your Own Bag?

Let’s Check It Out!

Not every luxury item is what it seems. With high-grade replicas becoming harder to detect, many people unknowingly own pieces that are not genuine. Even if your item came from a trusted source, it may not be what you think.

Whether it was purchased second-hand, received as a gift, or picked up online, how confident are you in its authenticity?

Pricing is outlined clearly at checkout.
