        "photo 1: the bag is covered in multicolored beadwork and satin\/textile panels, unlike Coach's typical leather, coated canvas, or signature fabric construction",

        "photo 1: no Coach identifiers are visible, and the materials place it outside the vintage Coach glove-tanned-leather population",
        "Condition: appears visually clean in the supplied staged photos, but condition is uncertain because the photos do not reliably show bead security, zipper function, odor, or hidden wear"
