Dose anyone know what pen Jamie Hewlett is inking with at 13.16?

I'm pretty sure he was using a standard hunt nib throughout his run on Tank Girl but then switched over to whatever this is. The most i could find was a a description on what he used to make pic related which described it as a "black ink pen", but i can't find anything else and it's annoying the shit out of me. I know you don't "need" whatever he's using hear to achieve similar line work but i have autism and want to know.
