        "photo 5: Interior is fabric-lined with multiple compartments and modern organizer pockets, not the unlined suede-back interior typical of many vintage Coach classics.",

        "The listing uses stock-style promotional images rather than detailed owner photographs, limiting verification of hidden labels and construction."

        "No Coach model is a reasonable match because no Coach identifier is visible and the bag's modern lined organizer-hobo construction does not strongly match the listed vintage Coach catalog styles.",
        "Condition: Seller states brand new; promotional photos show no visible wear, but actual condition cannot be independently verified from stock-style images."
