I like the shade and how it applies - glides easily. The glitter sometimes gets on my eyelashes and feels a little irritating. I’d consider getting another shade without glitter.

Goes on smooth, but doesn’t stay on as advertised. You will need a really good primer to get it to stay put.

This is my third eyeliner, I really like these liners, they glide on so smoothly. And good color variety. And within my budget. But most importantly, clean ingredients. Will purchase more of these in different colors.
