    My new go-to eyeliner.

    Very easy to apply! It doesn't say it's waterproof so I was worried but when I took off my makeup for the night, it took a makeup remover and makeup wipes to fully get it off. 10/10 recommend.

    Great

    This is the best liquid liner I’ve ever used. It stays on all day, the brush tip makes it easy to draw crisp lines, and the pigmentation is great.

    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
