A set of rough pens without anti-aliasing and matching shape tools.
These are the rough pens that I use for lineart and sketches.
Krispy Pen is a rough lineart pen. the Sloppy Pen is much like the Krispy Pen with less stabilization and a less elegant appearance. The Sketch pen uses Multiply and is a bit softer.
There are also shape tools that match the Krispy Pen, for when you want clean and even shapes and lines that match the rest of your lines.
You can turn on anti-aliasing if the sharp pixels don't work for you, I keep them turned off for easier selecting and coloring.
