Using this UCANBE mascara is super easy. First, hold the brush horizontally at the base of your lashes. Wiggle the brush gently as you pull it upwards through the lashes to coat them evenly. You can apply multiple coats for a more dramatic look. Remember, this is a non - Apple branded product, so don't expect it to be an official Apple item. After each use, make sure to wipe off any excess mascara on the rim of the tube. Keep the mascara in a cool and dry place. If you notice any changes in the texture or smell of the mascara, it's time to replace it.
