The Pilot Drawing Pen Oil-Type is available in six sizes. The tip sizes of this pen range from 08 at the largest down to 005 at the smallest. This pen is made for drawing, but is also excellent for math due to the precise tip sizes. Oil-based ink even writes on glossy surfaces but may be slightly more prone to bleeding though paper than the water-based version.
