It is meant to create a smokey eye. The eyeliner is really soft and slides on easily. It is so soft and smooth and easy to blend. I could easily only wear this eye liner blended well. I have never used an eyeliner that blended this easily.
There is one downside. The first time I wore it I noticed large raccoon lines under my eyes after about two hours. I guess something that goes on this easily also smudges easily below the eye. Maybe this should only be worn on the top eye lid.
