Designed to create fine hair-like strokes, this ultra-slim pencil expertly fills in patchy areas and defines your arches with natural-looking color. Mineral pigments resist perspiration and oil, providing long-wearing coverage that won't smudge or fade throughout the day. Koh Gen Do's signature T3 Oil and smoothing hydrolyzed silk condition your brow hairs as the pencil glides onto the skin without tugging.
