Benefit Cosmetics Mighty Fine Brow Pen in Shade 4 Warm Deep Brown is a precision brow marker engineered to create ultra-natural, hair-like definition with advanced triple-tip technology. Designed with three superfine 0.1 mm brush tips, this innovative applicator draws multiple micro-strokes in a single flick, instantly enhancing the appearance of fullness and structure.

Shade 4 Warm Deep Brown is a rich, warm-toned deep brown that complements deep brown hair and brows, adding depth and refined definition without looking overly harsh.

The highly pigmented formula delivers long-wearing, waterproof performance that resists sweat, humidity and smudging throughout the day. Despite its durability, the texture remains lightweight and buildable, allowing you to layer strokes gradually for subtle enhancement or more defined, sculpted brows. The triple-tip design helps fill sparse areas quickly while maintaining a realistic finish that closely mimics the look of natural brow hairs.

For best results, lightly shake the pen before use and apply to clean, dry brows using upward flicking motions that follow the natural direction of hair growth. The precise brush tips allow controlled shaping of the arch and tail while maintaining softness and dimension.

Benefit Mighty Fine Brow Pen 4 Warm Deep Brown offers detailed precision, rich colour payoff and long-lasting wear, delivering fuller, expertly defined brows with a natural hair-like effect that stays flawless all day.
