Koh-I-Noor "Progresso" silver gray
With this extremely robust pen the times of broken leads are finally over. All wood free consists of nothing but the lead and a silver finish for best grip and clean fingers. The writing thickness depends on the sharpness of the tip. If you place the pen diagonally, it is extremely effective to hatch wide and opaque surfaces. So the "Progresso" is very suitable for artistic drawing.
