Marlboro Eighty-Threes are full-flavor king-size cigarettes manufactured by Philip Morris USA. The "83" designation refers to the 83mm cigarette length, which falls between a standard king and a 100mm format, offering a slightly extended smoke compared to a traditional king size.

Marlboro Eighty-Threes are available in a hard box (BX) format, providing added protection for the cigarettes. Full flavor (FF) indicates the classic Marlboro tobacco blend with its characteristic robust taste. These are sold at Costco Business Centers as a carton, providing a cost-effective option for adult tobacco consumers.
