3.8 (10 reviews)
The Bionic Worker roller ball pens were designed by Stabilo for demanding professional use. The ink flows smoothly and produces a medium 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.

i really enjoy writing...
February 15, 2012
i really enjoy writing with the stabilo bionics. The ink doesn't come out totally solid like most liquid ink pens, and that's nice. There's real character in how the ink trails.

The handle is also very comfortable to hold, and the protruding dot on the barrel prevents the pen from rolling off uneven surfaces.

The pen also looks so damn good. The rubber body also feels so damn good.

I recommend.

I really like the feel of this pen. I enjoy rubber bodied pens greatly. This is a very well designed pen and it feels very good in the hand. The ink is dark and there is very little resistance across the page as you write. I will agree with other reviews I've read. This may be advertised as a 0.5 mm but the line is much wider. Compared to say the Zebra Sarasa I'd say the line width is between the 0.7 and 1.0 mm sizes. But I prefer bolder lines so this isn't an issue. Just don't buy this expecting a fine line. The other big issue is that for such a nice pen this is NOT refillable via any means. In this day an age, and for the price this is a bit no-no! I wish Stabilo would make one of these refillable and retractable. This would be awesome.

I like the feel of the rubber-like body, the clip is sturdy, and the whole pen has an interesting look. The thing I don't like is the line width is huge, and appears to easily be 0.7mm or even 1.0mm in width.

I wish I had scrolled all the way down to find the one review that says this pen writes like a 1.0. I made the mistake of seeing all the reviews with 4+ stars so I went for it. This is a case of faulty (contradictory) labeling on behalf of Stabilo. If you look closely it says "Medium - 0.5mm". If you know your pens, 0.5 is always sold as "fine" or "extra-fine", depending on the brand.

So... just to re-emphasize what the other reviewer stated: There is no possible way this even comes close to 0.5 or 0.7. To tell you the truth, I put it at a tad thicker than 1.0mm but only because of the result that's left on paper. I think due in part to the flowy, bleedy nature of the ink.

I think I should note that this pen feels marvelous in your hand! It has a nice non-slip, matte/rubbery grip to it. The pen length is a tiny bit on the shorter side -- so this would be a problem for people with larger hands.

Needless to say... this is in no way JetPen's fault. They do a wonderful job of being as detailed as possible with cataloging their merchandise! I should have paid closer attention. They are selling it as it is stated by the MANUFACTURER, so no fault of JetPens whatsoever.

My next order I will take a chance and go for the "0.3mm" version to see if that satisfies the thin point I am looking for in all my pens!
