True Green Menthol 100s are full-flavor menthol cigarettes available in box packaging. The "100" designation refers to the longer 100mm cigarette length, which delivers a slightly cooler, longer smoke compared to standard king-size cigarettes. True is a long-established cigarette brand known for its filtered, lower-tar menthol varieties, with the green packaging indicating the menthol variant. The box format provides rigid packaging that protects the cigarettes and is sold at Costco warehouse locations.
