I absolutely love this eye liner. It stays in place all day. The problem is that even with the specified sharpener, I can’t get a sharp point. If this eye liner was a twist up, I would give it 10 stars, but because I can’t get a sharp point, it gets three. I also can’t stand the black flakes I have to clean up after sharpening this liner to a dull point at best.

Happy I decided to try this! It goes on smoothly and easily blends when first applied. It really stays on all day too! I had no issues removing it with some eye makeup remover and warm water. I plan to purchase more shades in the future! It’s that good!

I love this liner but I can’t wear it with contacts for some reason it sticks to my contacts and really bothers me. Otherwise I love it
