TFD Brow Blade has one of the most unique slanted mechanisms you’ll ever see in the brow category. It effortlessly glides through the brow to create the illusion of naturally full brows but with precise hairlike strokes. The 1.5mm blade tip can carefully sculpt the brow and imitate real hair. Our little secret? There is a grinding tool tucked into the blade to allow the user to keep the blade tip sharp and as good as new for every use. The formula is a synthetic Japanese wax to ensure stability and prevent breakage and snapping. The product also is waterproof and long-wearing.
