It's easy to use and has a smooth application feel. If you quickly rub the rubber part at the back on the outer corner of your eye, you'll get a natural, beautiful line. Even after a while, your eyes won't turn panda-like, and it really lives up to its name, Double Wear. Even if you rub it after a while, it won't smudge, so even if you layer a darker eyeshadow on top, the eyeliner will still have presence. I was glad I bought it. I want to get the other colors too.
