DescriptionSpecificationsFrequently Asked Questions
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.

Like the other two reviews, I am disappointed with how thick it wrote. 0.7mm at the least. If you are looking for a ultra fine tipped roller ball pen I recommend the Pentel Eurogel 0.35mm Needle point.

I love the writing feel but the "fine" tip actually flows like a "medium." Wish it were refillable.

Just received this pen...

Just received this pen and I don't like it. Uniball discontinued the 0.28 mm blue Signo Bit so I need to find a replacement pen. This isn't it. I like the ultrafine tip and this rights more like a 0.7mm tip rather than a 0.3. I do like the feel of the body (a rubberized holding surface is nice) but when product is advertized as an ultra fine tip, the tip should be ULTRA FINE.

Love these pens! I first found one on vacation and was trilled to see JetPens has them! I got all four colors and love them all. The lines are thick and look as if a fountain pen was used. The colors are vibrant. Super great pen! Will definitely buy again.

As other reviewers have said, not really a very fine line. Definitely thicker than most .3's and even most .5s; more like a .7 or .8. Would not buy again.
