As a general use pencil these are great. Smooth, sturdy and the eraser is good too. These are also good for drawing and sketching. While your not getting a huge range of values (I'd recommend the staedtler lumograph rage for that) these are great for laying down guides, foundations, rough ideas. They really will go a long way. A great all round pencil that's superb value.
