        "photo 1-4: silhouette is a small utility crossbody with front and rear pockets, adjustable strap, top zipper, and snap\/zip compartments; it does not closely match the listed vintage Coach leather models.",
        "photo 5: polyester\/PVC material label and China origin support a modern non-Coach classification rather than a pre-2000 Coach leather era.",
        "Condition: Good based on visible pre-owned wear and loose thread on the label (photo 5); interior and exterior show no clearly severe structural damage, but bottom and corner wear are incompletely documented."
