The Saem Eco Soul Powerproof Ultra Slim Eyeliner

This is The Saem Eco Soul Powerproof Ultra Slim Eyeliner in shade BK02 Ash Black. Its slim shape makes it easy to draw thin lines, and since it doesn't smudge easily, I use it frequently. It's also great for the lower lash line, so I don't need to buy a separate one. Since it's an ash black rather than a pure black, the color isn't too intense, making it comfortable to use.
