VALENTINO Garavanti Rockstud Thong Black Sandals Size 6

Beautiful Valentino Sandals. These were gifted to me from a friend and only worn a few times. Can’t verify their authenticity since I didn’t buy them but they’re still so pretty. The bottoms of the sandals are practically brand new. Not worn at all. None of the studs are loose or missing. Right sandal has 3 chips, 1 on the middle, a small one to it’s right and another one 2 studs over it’s left. Left sandal has 2 chips both studs are next to each other The sizing says 37 but it also says 36. I’m a women’s size 6 and they fit perfect. There’s also two small marks on the side( see picture ) Any other questions. Please ask
