👉 Ballonsets are a type of ballpoint pen, often used in the United States and Canada. They consist of two separate balls, one larger and one smaller, which are held together by a rubber band or other means. The larger ball is used for writing on paper or in ink, while the smaller ball is used for drawing with the pen. Ballonsets were popular among students and writers during the 19th century, and they are still commonly used today.
