hi there are only a few pens I use when I’m not doing digital,
for thing lines stuff, a pilot precise V5 (I think it’s pilot, you can buy these in basically any drugstore with a pens section)
a Kuretake no. 30 brush pen, I used to use it for a lot of my comics but now I use it mostly for art and sketching (like the last few i posted) learning to use it well took a lot of practice but it’s a rewarding pen when you do
I hope that helps, the rest of my pens, alcohol markers for color/toning, and pencils aren’t that special really.
