Designed for use with Urban Decay's entire pencil lineup, the Grindhouse Double Barrel Sharpener features two sharpeners: a slimline sharpener for eye and lip pencils, and a larger sharpener for concealer and shadow pencils. The blades are made of durable steel infused with 1% carbon to prevent rust. This sharpener also works with most other brands' pencils and includes a plastic pick for cleaning shavings. Keep your pencils perfectly sharp with this dual-chambered makeup pencil sharpener.
