        "photo 1: clearly a leather handbag with a shoulder strap and woven construction",

        "Condition: Good\/Fair boundary; substantial edge fraying, dryness, discoloration, and worn strap attachment areas are visible in photos 1, 5, and 6; bottom hardware and base remain present in photo 4."
