Cigarette holders are elongated tubes designed to hold cigarettes, allowing users to smoke without directly touching the cigarette. They can be made from various materials, including plastic, metal, and even fine materials like ivory or glass. These holders can help reduce the intake of harmful substances by keeping the smoker's fingers away from the burning end. Historically, cigarette holders were popularized in the early 20th century, often associated with the glamour of Hollywood stars and the flapper culture. They come in various styles and lengths, and some are even designed to enhance the smoking experience by cooling the smoke or filtering out impurities.
