To meet the extremely high requirements of people who do a lot of writing, a pen must of course have all the attributes of a premium product and lead the field in quality, technology and design. Naturally, this is true of the STABILO worker, which offers a liquid-ink system and leading-edge bionic technology backed up by ergonomic design to make it fit ideally into the hand to prevent fatigue. All this without restricting the way the user chooses to hold it. The entire pen - and not just the usual grip area - has a velvety-soft, non-slip surface. A real asset for the writer, whose hand will be relaxed and comfortable even after hours of work. The rollerball tip allows him to write fast yet clearly. And of course the pen is filled with STABILO's high-quality, water-based ink in the popular office colours blue, green, red and black.
