Stabilo Bionic Worker Roller Ball 0.5 mm Review

Stabilo Bionic Roller Ball 0.5 mm

Do you have a brand of pen that you think is great looking and great feeling but there is something a little off that throws you for a loop? Stabilo is that brand for me. I keep coming back to them because they make a great looking pen but there is one thing that consistently makes me shake my head: their tip sizes are not based in reality.

I have mentioned on several occasions that tip size and line width are two separate measurements. The tip size is the physical measurement of the tip of the pen, while the line width is the width of the ink line on the page. For example, an 0.5 mm gel ink pen often leaves a line wider than 0.5 mm on the page, while an 0.5 mm ballpoint leaves a narrower line. Each brand has their own little intricacies that I have come to expect, but Stabilo blows them all out of the water.

The Stabilo Bionic Worker Roller Ball is marked on the barrel as an 0.5 mm pen. With a liquid ink pen such as this, I do expect a wider line than a comparable 0.5 mm gel ink pen, but this one is really wide. This is a line width I would expect from an 0.7 mm or 0.8 mm pen at the least. I should have been tipped off when I saw the word “Medium” on the back of the barrel. I have never seen an 0.5 mm pen marked that way.

This is a consistent experience across all Stabilo products I have tried but don’t let my rant dissuade you from what is actually a very good pen. I compare this pen to the standard Uni-ball Vision pen, and the Stabilo may be even better. If you like a wider line in your liquid ink pens then you should give this one a shot. Just don’t go in expecting fine lines.
