The Bionic Worker rollerball pens were designed by Stabilo for demanding professional use. The ink flows smoothly and produces a medium line great for everyday writing needs. A small nub on the side of the body prevents the pen from rolling away. The body also features a soft orange rubber coating, a translucent ink window, and an ergonomic 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.
