How Extra Fine is TWSBI ECO’s EF nib?

Entering the world of fountain pens...

Before purchasing the TWSBI ECO, I read a lot of reviewers saying that the EF nib wasn’t a true/Japanese Extra Fine. I couldn’t find a way to visualize what that meant then. I thought this visual comparison would be useful to first-time users.

My first fountain pen and ink:
TWSBI ECO Steel EF/XF nib
Noodler’s Polar Black

I was used to writing with extra-fine gel pens and the Pilot Hi-Tec C at 0.4mm was my favorite.

I hope you find this comparison useful.

*This video is not a review of the TWSBI ECO. I am very happy with the pen and how it writes.
*Just read that Noodler's Polar Black Ink, despite its several amazing properties, is prone to feathering according to other reviewers. That can surely affect this comparison. I didn't realize this until after my purchase. However, the Polar Black is the only ink I have right now. I might re-do this video with a different kind of ink soon.
