Thanks to its long history in Ancient Egypt and India, kohl may be the world's oldest cosmetic, with anthropologists dating the smoky eyeliner back to 3100 BC. It's since become a popular product for millions of beauty junkies, and appears frequently on runways and street style blogs. (Fun Fact: "kohl" is also the root word for "alcohol.")

Now Sephora takes their kohl eyeliner and slashes its price to $5 each. You can buy all of their colors - black, brown, blue, purple, and silvery lilac - for $25, or just restock your favorite shade without going broke.
As for some style inspiration, how about the gorgeous blue smoky eyes on Freida Pinto during her NYLON cover shoot?
