        "strap_construction": "photos 1 and 6: Adjustable narrow straps and a wide striped textile strap are visible; attachment construction varies by item. No vintage Coach strap construction is established.",

    "possible_model_reasoning": [
        "No Coach model is a reasonable match because the photos show contemporary mini-bag designs and no Coach identifier.",

        "Condition: approximately Good overall for the lot based on seller's statement that some pieces are not in perfect condition; visible exteriors do not show enough detail to assess interiors, odor, lining condition, or all corners."
