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 keep fingers clean and reduce the exposure to harmful chemicals found in cigarette smoke. Historically, cigarette holders were popularized in the early 20th century, often associated with glamour and sophistication in Hollywood films. They come in various styles and lengths, and some are even designed to filter smoke, making them a unique accessory for smokers.
