    "possible_model_reasoning": [
        "The bag is not a close visual match for the classic Coach City Bag, Court, Willis, Station, or other cataloged vintage styles because it has a modern open tote shape, double handles, side gussets, and a small rectangular clasp.",

        "Condition: approximately Very Good based on the visible exterior, with no obvious major tears or structural damage; bottom, corners, interior, odor, and lining condition are not shown."
