The thin tip on the Ultra Fine Brow Liner creates extremely fine lines that mimic the individual brow hairs. This makes it suitable for all brow shapes and instantly makes them appear much fuller. It also covers up any sparse areas. As it contains a retractable tip, this pencil does not require sharpening. The integrated grooming brush works superbly with the pencil. Perfect for accentuating your brows with extreme precision, but for a natural-looking result.
