The ergonomic, non-slip grip zone offers grip, support, and an instinctively correct writing posture, thanks to the finger indentations. This prevents premature muscle fatigue in the hand and pain or cramps while writing. The smoothness with which the rollerball tip glides over the paper ensures effortless writing. In addition, the ink flow is specially set for beginners, which prevents smudging of the ink and produces clean writing – even for left-handers. The ball in the tip only releases ink when it moves on the paper. Excessive ink release is therefore a thing of the past, so no more drips, stains, or blue fingers. Each refill comes with a new nib, so if a nib breaks, it can be replaced by inserting a new refill.
