The eyeliner goes on very smoothly. It looks pretty and I don’t need to worry about black circles under my eyes at the end of the day!

The dark brown color is so ideal and the fact that it’s waterproof, but somehow comes off easily when I wash my face is nothing short of a miracle. The only negative thing I would say is in the outer corners of my eyes, the eyeliner does melt a little bit, but that could be my eye cream. Anyway, I love this pencil and will continue to use it.

This is pretty waterproof but not perfect. Overall I still like it and have bought it more than once. The plastic coating is a little tricky for sharpening at first, but I got used to it and it sharpened fine.

This long lasting Eyeliner is the perfect brown shade for my eyes. I tend to avoid black eyeliner because makes my traits appear too heavy but this brown eyeliner looks great on me!
