Using this eyeliner is a breeze. Just hold the pen like you would a regular pen and gently glide it along your lash line. Start from the inner corner and move outwards for a smooth application. To avoid any smudging, let the eyeliner dry for a few seconds. If you make a mistake, you can quickly wipe it off with a cotton swab. For best results, keep the pen cap on when not in use to prevent the tip from drying out. Store it in a cool, dry place. This eyeliner is suitable for daily wear and special occasions alike, so enjoy creating stunning eye looks!
