My first impression was the tip is so precise and it does make a very fine job of lining my eyes. The felt tip is rather easy to maneuver and much better than traditional liquid eyeliners. It is the right shade of black for my dark brown eyes. The only thing that I didn't like was that it kinda fades out after a few hours. Overall, I like it.
My verdict: Revlon ColorStay Liquid Eye Pen is a good and easy to use eyeliner. I do recommend it.
