    "possible_model_reasoning": [
        "The front flap, handle, and crossbody strap establish a modern novelty crossbody handbag, but the piano-key motif does not correspond to a listed Coach model.",

        "Condition cannot be reliably graded because the images appear to be stock\/product photos and do not show the actual item's interior, bottom, or wear."
