        "The curved, zip-top hobo silhouette does not provide a reliable match to a specific Coach model, and no Coach style number or creed is visible.",
        "Seller describes the item as vintage-inspired and unbranded; this is weak contextual support for a generic western bag, not evidence of Coach manufacture.",
        "Condition: approximately Very Good based on visible exterior; leather appears intact with light creasing and no obvious major tears, but the interior, bottom, odor, and strap stress points are unassessed."
