Pen for learning art:

Professional cartoon pen and ink for hand-painted cartoons.

You can paint with an oil painting pen, and the effect is good. Generally speaking, it is best to choose wolfhorn chalk, which has moderate hardness and is easy to master. Nylon has good elasticity, hardness and brush strokes, but it absorbs less pigment. It is best to use high-grade nylon. Depends on which one you like.
