With just one set of Toppik brow building fibers, even the thinnest eyebrows appear instantly thicker, fuller, and more natural. Compared to eyebrow pencils or gels, eyebrow building fibers appear more natural and last longer than eyebrow powder. The best eyebrow makeup for full, natural-looking brows is this three-piece set, which comes with brow wax for shaping eyebrows, brow building fibers, and a special dual-end brush for applying the wax and fibers. What it does: This three-piece eyebrow kit teaches you how to properly shape your eyebrows. Three essential elements make the revolutionary Toppik Brow Building Fibers set special. Your natural brow shape is defined and set by brow conditioning wax. Fibers for brow building stick to brows, cover bald spots, and add color and thickness that lasts.
