Providing up to 12 hours of pigment, the KIKO Milano Ultimate Pen Waterproof Eyeliner allows you to create fine lines or bold, full flicks. A capillary system works to release an optimal amount of formula as you glide the pen across the lids, while its precision tip flexes to the contours of the eye for a crisp, clean finish. Water- and smudge resistant, the liquid liner promotes one-stroke saturation that stays put and won’t disturb your pre-applied shadows and shimmers.
