This Little Piece of Plastic Is the Key to Getting a Flawless Cat Eye

Musicians may notice that this tool looks similar to a guitar pick, but it's actually asymmetrical and made of a highly flexible silicone that can bend to the shape of your eye. One side is superstraight, one side is short and rounded, and the last side is very slightly curved, allowing you to create a wide range of liner looks, whether you're wielding a pencil, gel, or liquid formula.
