What is a "cosmetic sharpener"?

A cosmetic sharpener is a personal care tool specifically designed to sharpen various cosmetic pencils, such as eyeliner, lip liner, and eyebrow pencils. It features a small opening that accommodates the size of the pencil, allowing for precise sharpening. The sharpener's blades gently shave away the outer layer of the pencil, ensuring a smooth and precise tip for effortless application.
