Illamasqua Liner Brush - an ultra-thin brush for creating a defined line on the eyelid or in the waterline. This Illamsqua ultra-thin liner brush has tightly packed bristles, giving you ultimate control and enabling you to create defined looks with ease. Pro Tip From Illamasqua Head Of Artistry - Pablo Rodriguez: "Position the brush at a 45-degree angle against your eyelid, and apply the liquid or gel liner going across the lash line from the inner corner to the outer one. If you went too far, dip a cotton bud in makeup remover, and re-sharpen the ends."
