Starting with one eye, apply Lash & Go Magnetic Eyeliner from inner to outer corner of lash line. For extra hold apply two layers of magnetic eyeliner. Let the magnets do the work! Directly apply magnetic lash onto eyeliner when the liner is semi-dry. Magnetic eyeliner should be as thick as the magnets. Repeat steps on the other eye - no need to measure or trim, no lash adhesive needed. Note: Velour's magnetic lashes can be worn with or without mascara applied to natural lashes. If wearing mascara, apply to natural lashes first and allow to dry.
