    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.

    brown eyeliner

    I love how easy it glides on! I had never tried the brown but I will be buying again after I finish this one up!
