    Perfect affordable eyeliner

    Love this eyeliner it works perfectly. It doesn’t bleed, it doesn’t smear, and it last a very long time without smudging. It’s so affordable too!

    Pretty good!

    The brush and formula of this pen makes for a smooth application. It also lasts pretty well throughout the day. The color is less vibrant than I was picturing. More of a bricky red than an electric red. Overall I'm happy with it

    Love the Navy Liner

    This liner is great. It glides on easily and looks good with my light brown eyes. This is my first time with a navy liner, and I am impressed with this one. In will probably purchase more now that I know what a great product this is.

    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.
