This eyeliner is greatly enjoyable. The formula is super smooth, and effortlessly glided onto my eyes. in addition, the eyeliner itself is retractable, and comes with a sponge and a sharpener - making it super convenient to do a monochrome eye look. The sponge allows the product to be used as an eyeshadow which shows how easy it is to blend and smear, and the sharpener allows for a sharp liner look. The liner is multifunctional and the color looks really natural.
