This model was a "tip" from a colleague. I have tested this rollerball and equal ordered several times. He writes very soft and fits comfortably in your hand. The font width Furthermore ensures a good foundation for a beautiful typeface. And great as a holding pen for a long time (apparently good capacity in rollerball)!
In short: I like this rollerball pen and it is for me as a left-handed and professional prolific writers the perfect companion during the working day. I need nothing else.
