        "photo 1: Bag has a contemporary multi-zip satchel design with decorative tassels and bright silver-tone hardware, not a recognizable vintage Coach construction.",

        "photos 1-6: Surface has a uniform shiny, heavily textured appearance consistent with synthetic leather or coated material rather than visible glove-tanned full-grain leather.",

        "No Coach model is supported because the bag lacks a visible Coach identifier and its contemporary multi-zip satchel silhouette is generic.",
        "Condition cannot be reliably graded from stock\/lifestyle photos; visible exterior appears new or lightly used, but interior, odor, lining, and functional condition are unknown."
