Innisfree Powerproof Brush Liner

This is the Innisfree Powerproof Brush Liner. It comes in a brush color. It doesn't smudge easily, and the color is natural so it isn't too flashy; I've been using only this lately. It's easy to draw the winged eyeliner, and once applied, it doesn't smudge or come off after a few tens of seconds. I even used it while swimming this summer, and it was great.
