Why is it so hard to find yellow ballpoint pen. I mean yellow ink ballpoint pen. I have yellow fountain pen ink. Yellow gel pens. Yellow pencils. you can find yellow in almost all art supplies. And when you want ballpoint pens, where is yellow? I have visited many art stores. I have purchased these
None of then contains yellow.
I know its hard to get certain pigments. But is yellow that rare?
Nowadays, you can find sets of gel pens like these
Why we don't find sets like these without gel inks. Plain old ballpoint ink?
