Cotton swab

Cotton swabs (American English) or cotton buds (British English) or ear buds (British, Australian and South-African English) consist of a small wad of cotton wrapped around one or both ends of a short rod, usually made of either wood, rolled paper, or plastic. They are commonly used in a variety of applications including first aid, cosmetics application, cleaning, and arts and crafts. The cotton swab was invented in the 1920s by Leo Gerstenzang after he attached wads of cotton to toothpicks.
