        "photo 1: The bag has a generic woven textile exterior with black synthetic-looking trim and a front snap pocket, unlike classic Coach glove-tanned leather construction.",

        "photo 1: No COACH wordmark, horse-and-carriage mark, or recognizable Coach identifier is visible.",

        "strap_construction": "photo 1 and photo 4: Thin adjustable shoulder strap with small metal clips attached at the sides; apparent synthetic trim.",
        "stitching_description": "photo 1-4: Visible machine stitching appears generally even, though close stress-point and underside views are limited; the woven exterior is visibly frayed or fragile on one side."

        "The rectangular zip-top crossbody\/clutch silhouette is generic and does not provide a reliable Coach model match.",

        "Condition: Good\/Fair; the seller reports fragile or damaged weave on one side, and photo 2-3 show apparent wear\/fraying. Interior and hardware function are otherwise only partially documented."
