Demonstrator pens were originally furnished by manufacturers to dealers, so that the features of their products could be shown to potential buyers. The first demonstrators had openings cut in their barrels, and usually, their caps. These would typically allow direct viewing of the filling mechanism and the section-inner cap junction, respectively. Cutaway demonstrators were usually not fully functional pens, and many were furnished without nibs or with nonfunctional dummy nibs.
Modern demonstrator fountain pens are clear, or partially clear writing instruments that allow you to see the inner workings of the pen. Originally, the purpose of these pens was for pen manufacturers or pen sellers to show-off the desirable mechanisms of the pen that were not normally visible from the outside. They were not meant to be sold to the public. Some old demonstrator pens were non-functioning and even had holes cut into the barrel. Eventually, clear plastics came to be used to create very limited numbers of these pens and they became sought after by collectors. Their popularity grew, and now they are commonly used by many as daily writing instruments.

Most transparent demonstrators, however, postdate the general adoption of celluloid for fountain pen manufacture. Parker and Sheaffer both made fully transparent versions of their best-selling Duofold and Balance models in the early 1930s. Other demonstrators were only partially transparent, the transparency highlighting the pen’s special features. Examples include the transparent-barreled Parker Vacuum Filler demonstrators (showing the filling mechanism) and the Parker 51 demonstrators with transparent hoods (showing the collector).
