The following is a reprint from Wikipedia: ⚫︎KOOL is a brand name of cigarettes manufactured by British American Tobacco (BAT). All products manufactured are menthol cigarettes. It is also famous as the world's first menthol cigarette. The name comes from the initials of "Keep Only One Love" (from the leaflet enclosed with KOOL products, translated into Japanese as "to stick to one love"). It is also said to be an abbreviation of "Kiss only one lady," or "kick out old lady," but these are just rumors.
