Pull the cap straight off without twisting it, and sharpen the pencil before use to achieve additional precision. Line and shape the lips to achieve the desired shape. For a natural effect, choose a shade that resembles the lipstick. For a more defined, contoured look, choose a shade that is two to three shades darker than the lipstick. The lip liner can also be applied to the entire lips to achieve a matte lip color. Sharpen as needed with the ABH sharpener or a standard pencil sharpener.
