I never did quite figure this liner out. It is literally the consistency of a waterproof mascara. To use, you must click click click and wind the product up and through the pen to the slanted tip. After several clicks, the sludge appears, and does not distribute unto the liner applicator. Also, from the first use, I thought maybe I got a bad batch. Not so. It does not glide on as advertised. Instead you have to touch the product with your fingers. Then milk the sludge to the applicator tip. Finally, very carefully, try to line your eyes. You will be stuck with clumps and then a finger covered in waterproof mascara type matter that is almost impossible to remove. This product is not a pleasant way to line your eyes. I tried everything because I wanted it to work as well as the "TR" mascara. I thought it was me. It is just a terribly impossible product. If it was not for the price I do not think I would have went to all of this trouble. Most certainly, this eyeliner should come with a video tutorial DVD for this price. And even then, I have no idea if it will make you look beautiful. Not worth the hassle I went through; that is for sure.
