The TWSBI ECO Fountain Pen in Bahama Yellow is a transparent demonstrator pen that lets you watch the piston mechanism and ink level in action, finished in a bright, translucent yellow resin with silver-tone trim. It pairs TWSBI's accessible ECO line with a cheerful, warm-weather colourway that stands out on a desk or in a pen case.

Like the rest of the ECO series, this pen uses a piston filling mechanism with a notably high ink capacity, so you can go longer between refills. The stainless steel nib delivers a crisp, controlled line suited to small handwriting, note-taking, and everyday office work, where precision matters more than line width. The demonstrator body means the piston and ink chamber are always visible, making it easy to monitor ink level and see the mechanism at work.

The Bahama Yellow body is transparent, so you can see the piston mechanism moving and monitor your ink level at a glance, rather than guessing when it's time to refill.

Extra Fine lays down a narrow, precise line for small handwriting and dense notes, while wider grades give a smoother, more expressive stroke. Pick the option that matches your handwriting size.

Twist the knob at the end of the barrel to lower the piston, dip the nib into a bottle of ink, then twist the other way to draw ink up — no cartridge or converter required.

The ECO's piston mechanism gives it a notably high ink capacity for its size, so it can go longer between refills than many cartridge-based pens.

It's a piston-fill pen, so it draws ink directly from a bottle rather than using cartridges or a separate converter.
