Excellent
These pens are really nice to use and good substitute the more aggressive, alcohol based graphic markers in many situations. The colour range is great and the vibrancy on the page is really good. They can be used in combination with other materials and they don't bleed through the page as much as Stylefile or Copic markers. You have to content yourself with the brush tip though as they only come with that. It seems to retain its shape pretty well even after use over large areas though which is good, and it can give you much more delicate effects than a bullet or chisel tip.
