New black Gucci loafers

Authentic black leather Gucci loafers. New and never worn. Size 36.5 (6.5). Jordaan style from several years back. I am a true 6.5 and these fit me perfectly. Bought two years ago and never wore, in perfect condition. Comes in a size 37 box due to store mix-up. Some black smudges on the white shoe bags from storage. Poshmark will authenticate the loafers for free due to price point (in other words, you will be fully refunded if Poshmark finds they are inauthentic).
