I have, because I had to write some tests last year, long searched for a writer, with which it can be really easy and fast writing. This writer has ever definitely a small advantage. I have now presented him several times. A bit expensive I find the many different model names, I am also sold before. What I like most about this really Schreiber (signo 153 with 1, o mm lead). The bar is slightly wider but it really very soft.
