        "The seller's claimed 1980s era is unsupported by a creed, serial, Coach label, or clearly period-specific Coach construction.",
        "Condition: Good to Very Good; exterior is largely intact, but the strap ends show visible wear\/fraying and the interior has ordinary use signs. Bottom and stress-point details are incomplete."
