        "photo 2: exterior has a multi-color geometric striped\/blocked synthetic-looking body rather than the solid glove-tanned leather typical of vintage Coach classics",

    "possible_model_reasoning": [
        "No Coach model is a reasonable match because the bag has a modern geometric exterior, striped fabric lining, and multi-zip compartment layout without any Coach identifier.",
        "Condition appears approximately Very Good from the visible exterior and interior: no major damage is apparent, but bottom, corners, odor, and hidden wear are not fully documented."
