Using this Ben Nye eye liner is easy. First, hold the pen like you would a regular pen. For a cat - eye look, start from the inner corner of your eye and draw a thin line along your lash line, then extend it outwards at the outer corner. To get a full lash effect, use the fine tip to fill in the small gaps between your lashes. It dries quickly, so be careful not to touch your eyes right after applying. When you're done using it, make sure to cap it tightly to prevent it from drying out. Keep it in a cool, dry place. If it accidentally gets in your eyes, rinse immediately with clean water. Enjoy creating beautiful eye looks with this liner!
