Hands-Free Electric Pencil Sharpener: This is a truly automatic pencil sharpener. Insert the pencil, and the sharpener will grip and automatically begin sharpening. Once sharpened, the sharpener ejects the pencil. No need to hold the pencil during sharpening. Works Well with Colored Pencils: Colored pencils have softer leads than other pencils, making lead breakage common in electric sharpeners. Our sharpener is designed not only for hard pencils but also features a special function for colored pencils. When a colored pencil is inserted, the sharpener uses gentle force to prevent lead breakage. Built-in 2000mAh Rechargeable Battery: This electric sharpener comes with a 2000mAh lithium battery that can sharpen approximately 600 pencils on a single charge. It can also be used while charging. The USB cable ensures convenient charging from various sources (power banks, laptops, etc.). 3 Sharpness Levels for Multiple Occasions: This sharpener features upgraded adjustment parts for the pencil tip, allowing for 3 sharpness levels (sharp, medium, and blunt) to suit your needs. Sharpening Short Pencils: Like standard sharpeners, you usually need to hold the pencil while sharpening. Short pencils are difficult to sharpen in both electric and manual sharpeners. Thanks to its gripping mechanism, our sharpener can handle pencils as short as 2.5 inches, maximizing the use of your pencils before disposal.
