    "possible_model_reasoning": [
        "The long, shallow rhinestone flap silhouette and synthetic metallic finish fit a Y2K-style unbranded evening clutch rather than a listed Coach model.",

        "Condition: Good; visible scuffs, scratches, creasing, and edge wear are present in photos 3-5, while the gems appear intact."
