        "No Coach model is a reasonable match: the multi-zip contemporary tote and attached pouch do not correspond to the visible Coach catalog candidates.",

        "Condition: appears Very Good or better from the provided product-style photos, but corners, bottom, strap wear, odor, and actual material condition are not fully assessable."
