        "No Coach model is a plausible match: the novelty reindeer design, PU material, small dimensions, and lack of Coach identifiers point to a modern generic holiday crossbody.",

        "The seller-provided PU specification supports a modern non-Coach classification rather than a vintage leather Coach classification."
