        "photo 1: the lot consists of assorted textile, beaded, satin, faux-textured and leather-look small purses with no visible Coach branding or recognizable Coach construction",

        "Condition: generally Good to Very Good visually, but interior condition, odors, lining condition and functional closures are unknown; the brown clutch shows surface wear and the textile items show age-related discoloration or wear in places."
