is what it says on the tin and they are exactly that.
I was a bit apprehensive about spending a lot of money on some artists pencils but having done a lot of research on the different types by Derwent and other arty brands, I decided to settle for this set. The texture is extremely soft on the paper and the teeth (at least I think that's what they call it) shows through like crayon on paper. Having said that, they do give an intense colour when you add layers or apply firmer pressure. You can use a blending stump with them to give a smoother look and mix colours together to produce new hues.
Although they are very soft, you can sharpen to a fine point for detailed work but beware, I sharpened one too much and it broke sometime between use.
So far, I have used them to draw two butterflies but I'm pleased with the results. You can look at the art gallery on the Derwent website to see what they're capable of producing. They produce particularly striking results when used on black paper.
All in all, this is a very versatile set of pencils that I would highly recommend for those serious about their art and I'm very pleased with this product.
