Our eyeliner (graphite color) is carefully formulated from acrylate copolymers and ethylene glycol. Designed specifically to enhance water resistance and the longevity of makeup. The usage method is extremely convenient: Sharpen the pen tip before use to ensure it is sharp enough. Gently draw lines along the contour around the eyes to create a delicate eye makeup. Easily draw smooth eyeliner with a clear contour that is not easy to smudge. And it has a long-lasting color-locking formula, which can prevent sweat and oil and is not easy to cause makeup to come off.
