WAB Clear Fountain Pen Fine Nib (F) – Clear

Lightweight, bottle-ink ready, and designed for crisp daily note-taking.

The SERIO WAB is a lightweight, ultra-practical demonstrator fountain pen designed for easy, everyday writing. What makes this model stand out is that it comes right out of the package equipped with its own piston converter—allowing you to draw ink straight from your favorite bottle without buying extra parts or relying on single-use disposable cartridges. The fully transparent barrel gives you a front-row view of your ink supply, so you always know when it’s time for a refill (and your ink color gets to show off through the body). Up front, the stainless steel Fine (F) nib delivers a smooth, controlled line that stays crisp on standard paper, making it a reliable choice for planner entries, fast note-taking, or quick sketches. Finished with a sturdy black wire clip, it clips securely onto notebook covers, pockets, or pen loops for easy daily carry.
