        "photo 1: Front view shows an elaborate skull-and-crossbones centerpiece, studs, rhinestones, and ornate embroidery rather than a recognizable Coach design.",

        "photo 1-3: No Coach identifier is visible, so Coach manufacture cannot be supported from the listing photos."

        "Condition: Good to Very Good based on visible intact exterior and hardware; the interior, bottom, and functional closures are not fully assessed."
