What it is: A foolproof, felt-tip waterproof eyeliner that delivers silky carbon black color onto the eyes without skipping or smudging.Who it's for: All skin types.What it does: The ultra-fine applicator draws a perfect line every time, from a natural look to the most dramatic cat-eye, with a quick-drying, moisturizing formula that glides on and lasts all day. An ergo-dynamic grip allows for ultimate control and precise application.How to use: For easier placement on the lid, lightly map out how and where you want your line to go on your lid, then simply trace over it. Don't try to draw one line across the lid. Instead, draw short dashes at the lashline then go back in to connect it all together.
