I would definitely recommend this product!! I avoided using liners for a long time because they always have a tendency to slide around and smudge on my skin after the first hour. However, after hearing raves about bobbi brown's gel eyeliner, I decided to try it. Long wear, waterproof, and much more natural looking than a liquid eyeliner (too harsh)! I can make it as dramatic or natural as I want. The product comes in a glass pot. I use very little product each time, so it should last me a good many years. I chose violet ink, which is a beautiful dark purple/black color..
