        "photo 1: all three visible bags have contemporary generic silhouettes and no visible COACH wordmark, horse-and-carriage, creed patch, or hangtag.",

        "photo 1-2: condition appears approximately Very Good from the visible exteriors, with no major wear apparent; interiors, odor, lining condition, and strap condition are unknown."
