Kuretake Bimoji Brush Pen - Cadmium Scarlet 031

The Bimoji is Kuretake's workhorse brush pen, and the scarlet is a good argument for not doing everything in black. Strong enough to carry a whole piece, warm enough to sit beside ink without shouting.

Felt tip rather than bristle, which trades a little expressiveness for a lot of consistency. Easier to control if you are still building brush confidence.
