    Cool

    I've been testing out vivid liquid eyeliners and I wanted to try white.

    This product does what it's supposed to. It's not perfectly opaque. In some places, you may want to give it a second coat. It's a very smooth formula, easy to apply.

    It's not very smudge-proof. If you're like me and you rub your eyes a lot, you can mess it up pretty easily. Take extra care. (in the second Pic, you can kinda see where I smudged the inner corner of the right eye.)

    Overall, a good product.

    Good inexpensive eyeliner

    Just what I was looking for. Crisp color, doesn't smudge

    Numero Uno is #1! 🥰✨💖

    An eyeliner I’ve gone back to repurchasing many times! Numero Uno is very dark and stays on well throughout the day without any smudging or bleeding. I didn’t know this the first time so I want to let other buyers know, Numero Uno (black) is felt-tip and the regular black is brush tip. Both are great choices if you have a preference 😊

    black eyeliner

    I have purchased this specific color multiple times and I just went ahead and ordered enough to last me all year this time! They ARE that good.
