Authentic Coach product. Purchased at a Coach authorized retailer in Sendai, but it's in near-new condition, only tried on at the entrance. There are no scuffs or scratches. Size is 6.5c, which is equivalent to 23.5cm. I've included the size guide extracted from the Coach website, so please check it. Color: Black系 (Black-based) Heel Height: Approximately 6cm Toe: Pointed Toe Sole Heel Shape: Stiletto Heel
