Demonstrator Fountain Pens

Demonstrator fountain pens feature a clear or translucent barrel that lets you see the ink inside. Watching your favourite ink swirl and flow as you write is one of the great pleasures of the hobby, and they're also practical, giving you a clear view of your ink level so you're never caught short.

Demonstrators look particularly stunning with shading, sheening or shimmer inks, where the colour shifts and sparkles are visible through the barrel. Browse our selection below and pair yours with one of our fountain pen inks to make the most of the effect.
