First things first: prepare your eyes! Primer is optional, but if you want your makeup to last longer, you should do it. Set the primer with a translucent powder or eyeshadow. Shake the magnetic eyeliner and remove any excess eyeliner from the brush. The eyeliner line needs to be as thick as the lash band, otherwise they won't stick. Let the eyeliner dry for 2 minutes. When it no longer leaves any residue to the touch, you can apply your favorite pair of lashes.
