I am a student and use these pins for the school for writing homework, exercises, book entries, etc. My Favoriert is the pen with the color dark blue. This acts as Kulli- / filler substitute and met this perfectly - no dabs, no smearing (provided you do not wipe intentionally over the freshly written word). The stylus glides over the paper and does not scratch, write long is no problem for the Point Visco, neither Tuen hurt fingers, still fatigued hand.
Even the draw (school is not always exciting ...;)), they are limited in moderation. The colors have all very powerful and rich, but one should be careful, it is keeping the pen too long at one point fixed, the ink is expressed by fast.
Can only recommend these pins.
