        "photos 2 and 4: the rectangular frame handbag with kisslock closure is not a strong match for the listed classic Coach turnlock models, and no Coach identifier supports a model assignment",

        "Condition: Good; visible surface creasing and wear across the exterior (photos 1-3), with no major tears visible; bottom, corners, odor, and hidden interior condition remain incompletely documented"
