Featuring a precision brush, the MAC Brushstroke 24-Hour Liner paints on easily, creating sharp, controlled lines. The tapered pen glides across the lash line to deliver sleek definition, allowing you to switch between fine flicks and bold strokes in a single sweep. Smudge-resistant and long-wearing, the formula works to deliver rich colour that stays put throughout the day, and when it's time to remove, it washes away easily with warm water.
