Nature Republic Smudge Proof Eyeliner Deep Black

I often do makeup that emphasizes the eyeliner, and this product has a rich color that doesn't smudge. Since it is a brush pen type, it is easy to apply with a quick swipe, and it draws thin lines to give a sharp look. It was also the best value for money product I have used so far. I recommend trying it as an accent color when doing cool-toned makeup.
