        "photo 1: round bright-red bag with decorative quilted\/wavy surface and chain strap has no visible Coach branding or recognizable vintage Coach construction",

        "Condition: Very Good based on the visible exterior appearing intact with no obvious major tears or hardware breakage; interior and odor cannot be fully evaluated"
