Our Revlon ColorStay Eyeliners have a new, improved formula that glides on easily and stays where it should for up to 24 hours. Draw precise lines with the sharp pencil tip, or blend and diffuse eye makeup with the built-in smudger for a smoldering, smoky look. It's one versatile pencil eyeliner that can create classic liner styles like cat eyes, as well as high-drama looks. New improved formula stays where it's supposed to for up to 24 hours plus, it's waterproof. Get the drama and definition you've been craving from a pencil eyeliner with this lightweight formula. There's a built-in sharpener on the opposite end, so you always get precise lines (great for cat eyes). Ophthalmologist-tested, because safety always matters. Available in 8 intense shades.
