Using this eyeliner pen is a breeze. Just hold it like you would a regular pen and draw along your lash line for a precise look. For a thicker line, press a bit harder. You can also use it to create dots or other creative designs. When it comes to removal, start by rinsing your eyes with warm water. Then, take a little cleansing oil on a cotton pad and gently wipe away the remaining eyeliner. Keep in mind that this product has a shelf life of 3 years. Store it in a cool, dry place away from direct sunlight. Also, avoid getting it into your eyes. If it does, rinse your eyes thoroughly with water. And that's all you need to know to make the most of your eyeliner pen!
