Use the pen tip of this product to draw eyeliner on the eyelid. 2. Fill in the gaps between the eyeliner lines and apply a thin layer of eyeshadow evenly. 3. Flip to the built-in smuder for smudging. Moreover, it maintains makeup for a long time without fading easily, and its gentle formula cares for the skin around the eyes.
