1) Emulsion eyeliner: strong expressive force, not easy to fall off after coloring, and the drawing line is relatively smooth. However, because the thickness of the pen tip is limited, the thickness of the drawn lines is not easy to change.
2) Pencil-type eyeliner: easy to use and carry and low in price. However, its expressive power is weak, and it is easy to fall off after coloring, so it is suitable for short-term makeup.
