This is a really nice pen, but I need to get used to it. Yes, it is a drawing pen, 0.05 mm Staedtler pigment liner. My father also used Staedtler pens when he was a landscape architect, although the non-disposable ones. I was always very jealous of him for having those. I am not quite sure how the technology and the chemistry behind those pens work, but unlike ballpoint pen, the delivery of ink is always minimal and constant, so there is a better control of the line during the gesture.
