>>5806105nothing special, I mainly use the standard mechanical pencil of CSP since is the fastest tool for me to do lineart, and being fast is important to me (small line variation so easy to controll, and easy to fill in color)
when I have more time I use the standard gpen.
When I want to do more painterly stuff I use hyan pen, I think is from hyan-natsu but not 100% sure, I find myself well with that
