A ballpoint pen, also known as a biro[1] (British English), ball pen (Hong Kong, Indonesia, Pakistani, Indian and Philippine English), or dot pen[2] (Nepali English), is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e., over a "ball point". The metals commonly used are steel, brass, or tungsten carbide.[3] The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument;[4] millions are manufactured and sold daily.[5] It has influenced art and graphic design and spawned an artwork genre.
