Testing out the Noodlers black ink

I've been testing out the black Noodlers bulletproof ink with a few different pens.

Portrait done with a copperplate dip pen. A bit scratchy to work with, but can do lovely fine lines. The ink can be quite a startling black, or at least blacker than I am used to. So a fine nibbed pen works well with it.

 Tiny sketch done with a Noodlers Konrad flex pen, although I didn't use the flex feature much.
