This vintage LV Sarah long wallet is authentic but someone did previously install d-rings permanently to this to make it accessible as a crossbody wallet on chain. There is no serial number but heat stamp is available in photos. Will come with unbranded crossbody chain shown in photos. Does also have some scuffs because it is vintage and previously owned. Has original pull tag on inside zipper but you can see the wear on it. Review photos carefully. Still works really well and snaps and zips perfectly.
