Pencil and liquid eyeenilr have very different textures: while pencil eyeenilrs can easily be blended and removed, liquid eyeenilrs have a much stronger "stay power" and create sharp lines. Many people like to use pencil first and blend it out, or just as a template because it is more easily removed if you make a mistake. Then they may go over it with liquid eyeenilr to create a sharp line, which makes the eye shape more defined,efbbbf or simply because liquid eyeenilr does not rub off easily
