The Maybelline Marker Eyeliner Waterproof is a precise, felt-tip liquid eyeliner designed for smooth application and long-lasting wear. Its waterproof formula resists smudging and fading, making it ideal for all-day use. The marker-style tip allows for sharp lines, perfect for creating both thin and bold looks with ease. Suitable for sensitive eyes, it’s a popular choice for defined, smudge-proof eyeliner styles.
