Nice selection, I wanted to try PR American Blue and Noodler's Eel series. I'm more suspiscious about Noodler's Blue Black: will it stain demonstrator pens (like Bad Blue Heron did to my TWSBI 580)?
I honestly am not sure, I haven't tried Blue Black in a demo pen. Maybe someone else has some insight?
I've tried this and it stained. Not terribly, but seems permanent. Since it's a bulletproof ink, I'm pretty sure it will stain any material that has a cellulose component in it.
No white ink? haha...
