        "No Coach model is a close match: the visible western\/boho ornamentation, yellow lining, decorative perforations, tassel details, and whipstitching do not correspond to the listed classic Coach silhouettes.",

        "Condition: Good to Very Good based on visible creasing and use-related surface variation; corners, interior condition, odor, and strap wear are not adequately shown."
