Ballpoint pen

Posted on at

ballpoint pen, also known as a "biro"[1] and "ball pen", is a pen that dispenses ink over a metal ball at its point, i.e. over a "ball point". The metal commonly used is steelbrass or tungsten carbide.[2] It was conceived and developed as a cleaner and more reliable alternative to quill and fountain pens and is now the world's most-used writing instrument:[3] millions are manufactured and sold daily.[4] As a result, it has influenced art and graphic design and spawned an artwork genre.

Pen manufacturers produce designer ballpoint pens for the high-end and collectors' markets.

The Bic Cristal is a popular disposable type of ballpoint pen whose design is recognised by its place in the permanent collection of the Museum of Modern Art, New York.[5]
