Make Up For Ever #4K is a moderately cool-toned, dark green with a natural finish. It is a permanent eyeliner that retails for $17.00 and contains 0.04 oz.
Make Up For Ever #4K Khol Pencil ($17.00 for 0.04 oz.) is described as a "deep green." It's a rich green-teal with very subtle blue and teal micro-shimmer. The shimmer is just barely noticeable. It yields great color payoff in a single pass, which is always good news when it comes to an eyeliner. It's the closest I've come to finding a dupe to Prescriptives Blue Grotto. It's a bit greener than NARS Kaliste.
Especially adapted to sensitive and thin skin around and inside the eye, the Kohl Pencil gives depth and intensity to the eyes. Its particularly gentle formula is tolerated by the most sensitive eyes, its soft and smooth texture blends effortlessly and keeps the skin around the eyes hydrated.
