Benefit Cosmetics Mighty Fine Brow Pen in Shade 3.5 Neutral Medium Brown is a high-precision brow marker created to deliver realistic, hair-like definition with effortless control. Featuring three ultra-fine 0.1 mm brush tips, this innovative triple-tip design allows you to draw multiple micro-strokes in a single motion, instantly enhancing fullness and structure.

Shade 3.5 Neutral Medium Brown is a balanced medium brown tone developed for neutral undertones, making it ideal for naturally medium brown brows that require definition without pulling too warm or too cool.

The richly pigmented formula offers waterproof, long-wearing performance designed to last up to 24 hours. It resists sweat, humidity and smudging while maintaining crisp, fine strokes that mimic the look of real brow hairs. Despite its staying power, the texture remains lightweight and buildable, allowing you to layer gradually for subtle filling or more sculpted, defined arches. The felt-tip triple applicator ensures controlled, precise placement, making it easy to target sparse areas and refine brow shape with detailed accuracy.

For optimal results, gently shake the pen before use and apply to clean, dry brows using light, upward flicking motions that follow the natural direction of hair growth. The superfine tips create soft, believable strokes that blend seamlessly with existing hairs.

Benefit Mighty Fine Brow Pen 3.5 Neutral Medium Brown combines advanced triple-tip precision, neutral-toned definition and long-lasting wear, delivering fuller, refined brows with a natural, professional finish that stays intact all day.
