Originally, Japanese Tombow is a top-quality, liquid-filled product that has been slightly modified and dried out to make it suitable for graphite shading and has become our favourite drawing tool.
The tools made with two tips.
With brush end, you can draw fine, soft shadows. (E.g. eye, mouth, nose shading)
The other end is a 0.8 mm thin, hard, round tip with which small points (e.g. skin pores), as well as thin shadows (e.g. iris spots), can be drawn perfectly.
