Using these white eyeliners is a breeze. First, make sure your eye area is clean and dry. Then, gently hold the eyeliner pencil and draw a thin line along your upper or lower lash line. You can make the line as thin or thick as you like for different looks. For a more dramatic effect, you can also use it to line your waterline. When you're done with makeup, remove the eyeliner with a gentle eye makeup remover. To keep these eyeliners in good condition, store them in a cool and dry place, away from direct sunlight. Don't let the pencils get too hot or cold, as this might affect their quality. Also, remember to keep the caps on tightly to prevent them from drying out. These eyeliners have a shelf life of 3 years, but it's best to use them within a reasonable time for the best results.
