I probably use about half of the colors. That's how much I like them. This eyeliner is a little thick, so I use a thin-tipped liquid eyeliner around the edges of my eyes (copying Yusuke Kawakita's idea). It doesn't smudge or pool in my double eyelids, even after a few tears. I don't think I've bought any other products so many times. However, Stay the Night does stick to my lower eyelid after a short time, turning it into a panda-like mess. Maybe it's just me, but... This eyeliner with pearlescent content doesn't bleed underneath, so I use almost all dark pearlescent colors. I especially recommend Hellvent and Isn't It Ironic?. Both are not affected by personal color or eyeshadow color, and are particularly durable. Hellvent is a vibrant, deep green, but it blends in surprisingly well!
