This pen is very comfortable to hold, thanks to the rubberised grip zone it does not slip away and he writes easily and fluently. Indispensable he is for me, because you can write to him also very small and clearly despite the Mine strength of 0.7. I solve Sudokus passionate heavy, which is not possible without auxiliary numbers. For this pen is ideal, partly because he writes so well, but also because he brings an eraser same that you can use to remove even single auxiliary figures, because it is so fine. The quality of the pen is also very good. I use it for years and he is still "like new".
