On my quest for the perfect pen to use when drawing party caricatures, I overspent and bought a Pentel Arts Color Brush......what a mistake! In my opinion, these so far are the worst brush pen I've tried....bar none. ink is hard to flow properly, you have to squeeze the handle ( WHO thought of that?). Messy and sloppy lines are all that I got from this pen. In my opinion, a total waste of money on my part, and I have tried tens of thousands of drawings with many other brush pens.
