The color is absolutely gorgeous. Since my eyes have a slight brown tint, I prefer brown eyeliner over black, and this one has a particularly beautiful brown shade among brown eyeliners. It applies smoothly for a rich, beautiful line, making it easy to create the perfect eyeliner look.
There's a bit of smudging under the aegyo-sal (the puffy area under the eyes). While friends with less prominent aegyo-sal say it doesn't smear for them, my family members and I notice that by evening, the eyeliner has smudged in that area.
To reduce smudging, try closing your eyes and spraying a makeup fixing mist a few times.
