Hello @erosaerik.art! Thanks for asking.
I'm using very old watercolor pencils from Faber Castell. But keeping then dry because they are already very soft. When I say very old It means they actually have about 15 / 20 years old, from the time I was in college. I just rediscovered them in the basement visiting my parents house during the lockdown. I did a previous post about this cool story you can check in this link
