TWSBI Go Clear - Fine Nib

The GO is TWSBI's most affordable pen, and it earns its place on the shelf not by cutting corners, but by doing one thing differently: the filling mechanism. It's the easiest ink-filling experience in our whole pen lineup, which makes this the ideal first fountain pen for someone who's a little intimidated by the whole thing.

Most piston pens require you to twist a knob to draw ink up into the barrel. The GO skips the twist entirely. Here's how it works:

1. Unscrew the barrel to expose the plunger
2. Dip the nib into your ink bottle
3. Press the plunger down, then release
4. The spring does the rest as the ink fills the barrel automatically

That's it. Press and release. It's genuinely satisfying, and it makes the whole "filling a fountain pen" experience feel less like a procedure and more like a party trick.

The same mechanism also makes the GO incredibly fast to clean, just press and flush with water a few times. If you're someone who likes swapping inks often, this is a real advantage.

Please note: Ink is NOT included

A quick no-brainer guide in choosing nib sizes in an overly complicated fountain pen world:

If you write small, go with an EF
For the normal writer, F is the most popular
If you tend to lean on a bigger font, M will be perfect
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stub nibs are italic in writing style (have a special card or invitation to write?)
