The Bionic Worker roller ball pens were designed by Stabilo for demanding professional use. The ink flows smoothly and produces a fine line great for every day writing needs. A small nub on the side of the body prevents the pen from rolling away. The body also features a soft rubber coating and is ergonomically shaped for writing comfort. The high-quality tip is made of nickel silver (a copper alloy with nickel also known as German silver) and gives an extremely smooth writing experience while dispensing the latest Stabilo bionic liquid ink technology.

Note: Liquid ink rollerball pens typically write wider than a similarly labelled gel or ballpoint ink pen. This 0.3 mm rollerball pen writes similarly to a 0.5 or 0.7 mm gel pen.

I absolutely love this...

I absolutely love this pen. It is true that it lays a somewhat heavier line than expected of a .3mm pen, but it is soooo smooth. I like the slightly hefty size and feel of it and the rubberized case, although if you are one who slips your pens in and out of a shirt pocket frequently, the rubber case will become a nuisance. Great pen. And how often do you get such great pen in interesting colors?

Very smooth-writing rollerball. Comfortable to write with. Good choice of colors. Thickness maybe misleading to some. However, the thickness can't be taken absolutely, it's all relative.
This pen feels great...

This pen feels great in your hand, the ink flows great and is a nice emerald color. Why a bad review? This is definitely not a .3mm pen. It's great if you want a ~1mm pen, but it's definitely not a .3mm.
I have both the .3 mm...

I have both the .3 mm and the .5 mm and I would agree with one of the other reviewers that these pens write a bit wider than the advertised nib. So the .3 mm is closer to a .4 mm or a .5 mm and the .5 mm is closer to the .7 mm.

That being said, I like the .3 mm a lot. I find the .5 mm to be somewhat smoother to write with, but I prefer with width of the .3 mm on paper. If you could merge the .5 flow with the .3 size, it would be a perfect pen!

I would have to say if you are looking for a true .3 mm, then I would go with a Pilot or Mach 3, something that is closer to a .3. But if you want a really nice pen for this price, then absolutely buy this pen!
Just received this pen...

Just received this pen and I don't like it. I wanted an Ultra fine green pen and decided to give this a try. The grip is nice but the ink comes out more like a 0.7 mm tip and not a 0.3 mm tip. Not worth the time or effort to return but I definitely will not be purchasing any more. If you like a medium tip pen, this may be for you. But I left and do not have great penmenship so I NEED an ultra fine tip pen. With a nice feel to the body, I just wished they delivered on what they advertised.
