Pen

A pen is a writing implement used to apply ink to a surface, usually paper, for writing or drawing.Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in the ink. Ruling pens allow precise adjustment of line width, and still find a few specialised uses, but technical pens such as the Rapidograph are more commonly used. Modern types also include ballpoint, rollerball, fountain, and felt or ceramic tip pens.
