We cannot provide any authentication.
We, at SellHound, create listings based on the brand logo, style number, and attributes shown in the photos and notes, but cannot provide any authentication.
We are not authorized and trained in the authentication of items but if we suspect that an item you have submitted may be counterfeit, we will reach out via an app message to advise you, before we create the listing.
If you suspect an item may be counterfeit, you should remove it from eBay and have it professionally authenticated, as it could result in an eBay action against your account.
There are many authentication services available where you can send detailed photos of the item for a fee.
