        "photo 4: handle and body construction are woven straw, with no visible Coach-specific hardware",
        "photo 5: visible fraying and loose fibers are consistent with a handmade straw tote rather than evidence of Coach manufacture",

        "No Coach model is a reasonable match because the bag is a floral raffia\/straw tote without leather Coach construction or identifiers.",

        "Condition: Good\/Fair; photos 4-6 show substantial fraying and loose fibers around the handle, opening, and edge areas; interior odor, mold, and full bottom condition are unknown."
