Do you know beautyblender? It’s the company that brought you this pink miracle sponge that blends makeup beautifully. And it’s especially handy, if you’re on the whole contouring train. Now the brand has a new product, and it’s so simple, you’ll kick yourself for not thinking of it first. It’s called Liner Designer, it’s also pink, but this baby gives you an idiot-proof solution to getting perfectly lined eyes (and lips).

As you can see, it’s basically a slightly larger-than-average guitar pick. How it works: you warm it up in your hands, and then pick the style you want (short round, straight-laced or curvalicious). Then either hold it to your lash line, the outer corner of your eye or eyelid, or you can just let it stick to the area of your choosing (that’s where the warming comes in handy). It’s almost like a protractor, if you can remember using one of those in school.

Once you’ve placed it to your liking, it is as simple as gliding your liner along the edge. And when you’re done? Just wash it in the sink and let it dry. It’s available in March at Sephora for $23.
