Very great, comparatively favorable crayons

So I have for my education (design of technical assistant) to buy for a project Polychromos because me from Faber Castell but were the original too expensive I looked for a cheaper variant and came across the KOH-I-NOOR crayons.
Price comparison, about 30 euros for 72 pens and Faber Castell you get for almost 30 Euro grade times 24 pins ...
That was for me the impetus then these pins really try.
I was really excited! All pens were sent into so small cardboard boxes and I've tried it immediately, (even on the box itself;)) And on the darker box shone the colors really nice.
The abrasion is also comfortable and I have also drawn the comparison with Polychromos von Faber Castell of classmates and hardly noticed a difference. The best I could thus draw on something rougher construction paper. The only 'disadvantage' for me was to create the 'dark' images, sad moods, etc. are difficult, just simply because the colors are so intense and bright.
So for me are really good pins to be measured price (At least just for my needs. I use them, among other things now also a hobby for anime character images.)

I hoiffe I could hereby helofen a bit when deciding :)
