        "photo 1: Decorative wood beads and rope-style straps are generic boho construction rather than Coach-specific features.",
        "photo 4: The bag appears lightweight and fabric-trimmed, further arguing against a classic Coach leather model.",

        "The visible natural-fiber construction, rope straps, and wood-bead accents do not match the material and construction profile of the vintage Coach catalog.",

    "possible_model_reasoning": [
        "No Coach model is a plausible match because the bag is woven straw-like material rather than a Coach leather or documented Coach signature-canvas construction.",

        "Condition: Good; visible wear and aging are present on the woven edges and strap areas, while interior condition is not visible."
