    "possible_model_reasoning": [
        "The frame-and-kisslock silhouette is a generic vintage-inspired handbag and does not closely match the listed classic Coach turnlock models.",

        "Condition: approximately Very Good to Excellent visually; the exterior appears unused or lightly handled per the seller's 'new without tag' claim, but interior and odor cannot be fully assessed from photos."
