NOTICE - If you have any question or suggestion, please feel free to contact us. We are kind to give you a satisfying answer. WORK WELL - Extra strong hold for lashes. We invited 25 volunteers to use our new magic eyeliner, even in the case of high winds, the false eyelashes still hold well. EASY TO USE - Used the same as magnetic eyeliner, you only need to draw an eyeliner to attract the eyelashes(Don't need magnetic eyelashes). NO MESS & WATERPROOF & ANTI-SMUDGE - Our magic liner is long-lasting, anti-smudge and waterproof. You can use it instead of magnetic eyeliner and eyelash glue.
