The chalk itself is high reasonably high, on a wet table lubricate the colors however partially enormous. Some colors, such as yellow, orange and light blue glow beautifully, while others such as brown, red and a strange light purple rather go under. Then you have to pay special attention as a teacher at the making of panel paintings. What I found quite stupid: I have, Dub I am leaning against a picture of the South African flag. Beautifully colorful, especially on white fabric. Unfortunately, even after washing :(
It was very unfortunate that the chalk was totally shattered by the transport. This of course is not a quality characteristic, but nevertheless: Purchases chalk rather in the business and transports them gentler than the German Post;)
