This 2-way combination is perfect to achieve a strong, defined brow look. The waterproof polymer formulation is ultra-resistant to water, sweat, sebum, and smudge. Our pencil is specially formulated with a harder texture and releases its colour pigment when it interacts with oils in our brow hair. Formula layers on perfectly without clumping up with brow hairs for even application. Fine-tip brush draws precise lines for your brow ends.
