Faber-Castell Free Ink Rollerball Pen 0.7

Faber-Castell Free Ink Rollerball. Not a free pen but ink that's free in the pen body rather than soaked into fibres in the barrel. This, combined with the advanced feed, ensures a constant flow of ink right down to the last drop. And the window in the barrel means you can see exactly what's left.

Conical tip writes a 0.7mm line.
