Christian Dior Crayon Eyeliner Waterproof is a long-wearing, smudge-free eyeliner that's not afraid of water! Each classic shade glides on with precise, mistake-proof ease. A blending brush-tip and a sharpener attached. Backstage Beauty Tip: Add definition to eyes with a fine line of Dior Waterproof Eyeliner and a swipe of Diorshow Mascara. Intensify this look for night by adding extra liner and mascara to the outside corners for a sexy cat's-eye look.
