M168. Tombow Fudenosuke Soft Tip Brush Pen.
These extra fine brush tip pens have a small but flexible tip that can create both thin and thick lines. Ink won't bleed though most papers. A nice choice for brush lettering beginners, and a great tool for seasoned calligraphers and illustrators as well. These new pastel varieties are great for lettering on both dark and light papers. White can also be used for highlight effects, and pastel ink can be layered to create more opacity.
