text: Ballpoint pen (also “biro” and “ball pen”) is a writing instrument that has a metal ball at its point which rolls and moves ink from an internal reservoir to the surface on which pen writes and, at the same time, works as a buffer between the ink in the reservoir and the air outside and protects this ink from drying.
