The Infaillible Brows 24h Filling Triangular Pencil by L'Oréal Paris ensures expressive brows all day, every day. The gentle triangular tip visually fills in the brows for a natural finish with up to 24 hours of hold. The retractable tip of the brow liner allows for filling in the brow and clear definition through the angled tip. The texture is particularly lightweight and allows for even application.
