What it does: A liquid pen-style marker to color and style brows. Why it's great: Tapered tip creates fine, hair-like strokes of a smudge-proof, long-wearing formula that dries quickly and is easily removed with soap and water. Fine-tipped brow pen features long-wearing formula. Applies with ease, clinging to both skin and hair for a subtle, natural look. Dries quickly, lasts all day and is easily removed with soap and water. Use as a base to increase your current brow makeup's staying power or to fill in sparse areas for a fuller look. How to use: Shake pen before each use. Apply following the natural shape of your brow. For darker color, add another layer. Where brow hair is sparse or missing, apply directly to skin in short strokes. By Anastasia Beverly Hills.
