        "photos 1-6: no creed, serial, wordmark, hangtag, or other Coach identifier is visible; this is not an authentication determination",
        "Condition: Good; visible edge wear, surface scuffs, darkened leather, and general use marks are present in photos 1-6; lining appears intact, but odor and hidden damage are unknown"
