The pins have which makes a harder tip than copics dealing with them more difficult.
However, the colors can be good nevertheless well and spread everywhere, also the painting over of colors works well.
Those who do not bother to the upper points, these pins can buy confidently. Depending on what you want to use these pins are quite favorable and sensible buy than the more expensive option of Copic.
My personal conclusion is, however, that I would have bought rather less selected colors of Copic in retrospect, than this set.
This is made up of above-mentioned deficiencies and the fact that I will probably never use some of the colors in this package / rare.
