Roller Ball Pens
Why do engineers use felt tip pens?
I am an engineering major, and I've realized that a good number of my professors use felt tip pens in their work. As a high school student, I was told to do my calculations in pencil. In college, I've been using most of my work with ball point and roller pens.
Because those pens are cheap...
