Additive Pens Double Helix Fountain Pen in Clear Demonstrator

What could make a transparent demonstrator fountain pen more fun to use? Jerry Tong answered this question with an infusion of modern technology. Introducing Additive Pens, the first commercial 3-D printed fountain pen. The lengthy clear barrel is printed with a design that makes watching ink slosh around on the inside simply mesmerizing. In an effort to preserve true transparency, the caps and front sections are machined from solid rods of clear acrylic resin. A German-made, Jowo #6 size stainless steel nib is installed for an excellent, out-of-the-box writing experience.
