I think also worth noting that some colors are duplicated. It is blue, green, red and black. Which sounds exactly can be seen my picture on which I have all the pins painted on paper. The arrangement is such in the package. (Top row -> Upper position)
The Neonstifte have an ink that can be compared with highlighters. They are not as strong as the other colors, but a nice touch.
I find that this selection is not intended for normal use in schools but rather for cartoonist, manga artists and related art forms that use striking colors. Colored sketches can be thanks to the tip shape also make good because the line width depends on the bracket. So you hold the stylus just touches the tip paper and there is a thin line drawn. If one uses the side of the tip, a wider line is drawn.
In any case, this kit is recommended and in my case a great Christmas gift!
