Marlboro Slate Menthol 100's Box is a full-flavor menthol cigarette from Philip Morris USA, sold in the classic hard-box format. The "100's" designation refers to the longer 100mm cigarette length, which provides a slightly extended smoking experience compared to the standard king size. Slate Menthol is part of Marlboro's menthol line, offering a cool, refreshing menthol character balanced with Marlboro's signature tobacco blend.

Each box contains 20 cigarettes. Costco typically sells cigarettes in carton quantities (10 packs per carton), making it a value-oriented purchase for regular consumers of this product.
