        "photo 1: Exterior has pebbled faux-leather appearance and a large modern hobo\/tote construction rather than vintage Coach glove-tanned leather.",

        "lining_description": "photo 2: Dark olive-brown fabric lining with multiple compartments and interior zip pockets is visible.",
        "strap_construction": "photos 1 and 6: Two padded wrapped handles are visible; side hardware suggests a detachable shoulder strap, but the full strap is not shown.",
        "stitching_description": "photos 1, 4, and 6: Visible machine stitching is generally straight and evenly spaced; construction appears modern and mass-produced."

        "Condition: Like New to Excellent based on clean exterior and intact visible stitching, though interior, odor, and full strap condition are not fully documented."
