Writing
Instruments - Ballpoint pens
IThe
most common style of pen is the ballpoint. The ballpoint pen uses
an oil based ink which is spread across the paper by a polished
steel ball. Ballpoint ink only sits on the surface of the paper,
so very little is used in writing. For this reason ballpoint pens
will write the farthest on a refill. In addition, the ballpoint
can take the most abuse of any writing instrument, and is useful
in applications where the pen will be under a lot of pressure, such
as making multiple copies. Ballpoints are also available with pressurized
refills which allow them to be used at odd angles or upside down.
