Using this eyeliner pen is easy. First, hold the pen like you would a regular pen. Then, start from the inner corner of your eye and gently glide the pen along your lash line to the outer corner. For a more dramatic look, you can add a wing at the outer corner. When using, make sure your eyelid is dry and clean. Avoid getting the eyeliner in your eyes. After use, always cap the pen tightly to prevent it from drying out. Store it in a cool and dry place. If you accidentally get it on your skin, you can use a makeup remover to clean it off.
