Why A Demonstrator?

Demonstrator fountain pens have existed for nearly a century. They were originally never meant for public consumption. Manufacturers would send them to retailers to show their customers what the inside of the pen looked like.

But the unconventional look of these pens soon had collectors willing to pay

Demonstrators have become wildly popular with writers and pen enthusiasts. While most demonstrator pens exist in their own ranges, some proprietary fountain pens even have a demonstrator option.

Most major pen manufacturing companies are making their own demonstrator fountain pens to keep up with the demand.

Another great feature of these pens is that they’re highly customizable. You can use the contrast of color between your pen and its ink to help it stand out in your collection. You can even swap out the nibs with relative ease to suit your needs.


  • Identify problems easily
  • Monitor ink levels
  • Highly customizable


  • Not as appealing with ink cartridge
  • No sleek finish


If you are a fountain pen fanatic, and thrive on understanding the inner workings of how these nifty writing tools work, dabbling in demonstrator fountains will ignite your imagination and take your writing passion to a whole new level. The 6 fantastic products above are a great starting point and will not disappoint.
