These are the Harry Potter wand inspired makeup brushes sold by Storybook Cosmetics. The metal brushes are sold in a set of five for $55, which is $11 apiece but you can't buy them separately you have to buy all five. They're modeled after the wands of Harry, Ron, Dumbledore, Hermione and Voldemort. I'm not sure how I feel about using a makeup brush modeled after Voldemort's wand though, that guy was ugly as shit. He should have cast a nose spell on himself, then maybe he'd have the self confidence to stop acting like such a jerk.
Keep going for one more shot.
Thanks to Stephanie B, who wants a makeup brush with a samurai sword handle.
