Two pens that I made to test out my homebrewed textures. They're pretty fun to work with.
Pretty simple to use. Pressure-sensitive with some velocity settings. Tilt is possible, I just don't have it enabled, but you can turn it on if you so please. All materials were hand-drawn by yours truly.

These are pretty good for linework and rough outlining, which is what I use them for, but you could sketch with them if you like more solid / bold sketches.
Part of an illustration I did with homebrew 002 crunchy is shown below.
