I have marked with this set for many portraits and appreciate the wide range of different mine very strengths. The graphite crayons I hardly use what is probably because that I do not have to do with large areas. But the different pencils and graphite pencils I appreciate very much. Even the practical paper wiper and the pin-shaped eraser, which is super to erase small areas or to set highlights. By Knetradiergummi I need but only befriend yet;)
