Kuretake Disposable Pocket Brush Pen - Medium

I suspect this pen is really more suited for calligraphy rather than drawing applications. I had hoped it could be a decent pen for drawing caricatures and cartoons quickly thanks to its wider nib. Unfortunately the ink flow is rather slow, so the thick lines tend streak when drawing long strokes at faster speeds. Good trait for making Kanji characters in a controlled manner, but rather disappointing performance as a drawing tool.
