This foolproof eyeliner is infused with high-impact pigments that deliver smudge-proof saturated matte color. The weightless inky pencil features thermo-sensory technology that allows this formula to transform from a solid to a liquid upon contact with skin creating a flexible water-resistant film that lasts up to 24 hours. The micro-thin lead on this next-generation pencil can be dotted between lashes or glided across eyes with remarkable precision and no skipping. Available in ten shades inspired by sumi ink sticks used in traditional Japanese calligraphy. Dermatologist and ophthalmologist-tested. Direction of use Twist up the tip approximately one millimeter (one or two clicks) and glide across lash lines. Replace cap firmly after use.
