        "Silver-tone frame hardware, a fully lined interior, and the structured frame design are not internally persuasive for a typical vintage Coach glove-tanned classic."

        "Condition: Good; visible handle-edge peeling\/wear in photo 4, while the body and base appear intact. Interior condition is partly shown but odor and hidden wear are unknown."
