Never used , plastic protective seal still attached to the clasps 100% authentic - Poshmark will authenticate any purchase over $500 before it is forwarded to the buyer. This strap came with my Neverfull BB which I purchased on a trip to Spain, however I do not have a need for this kind of strap and prefer to use my other leather/non fabric straps ! I will include a dust bag and box from one of my other Louis Vuitton items.
