I had heard good things about these pins; but was still sekptisch whether it would be really worthwhile to buy these pens. In a test on drawing fell: very light inking and bold colors. The brilliance of the colors of pens exceeded my other (Steadtler Noris Club) to a Vielfaches.Vor especially if you draw several layers one above the other arising rich colors. Very nice! The only drawback is that wear the pins through the soft air of extremely fast. Especially for very thin lines Nachspitzen required repeatedly. Fortunately, you can buy more individual pins at Farber Castell or various Internet dealers, so is the rapid consumption now is not necessarily a problem. But overall there are wundererbare pins. I recommend these pens all advanced hobby subscribers!
I have uploaded the test drawing among customers photos.
