Hands-free Electric Pencil Sharpener: This is a truly automatic pencil sharpener. Insert the pencil, and the sharpener will grip and sharpen it automatically. After sharpening, it will eject the sharpened pencil. No need to hold the pencil during sharpening. Works Great with Colored Pencils: Colored pencils have softer lead than others, often breaking in electric sharpeners. Ours is designed not only for hard pencils but also features a special function for colored pencils. When inserted, it sharpens with gentle force to prevent breakage. Built-in 2000 mAh Rechargeable Battery: This electric sharpener comes with a 2000 mAh lithium-ion battery that can sharpen up to 600 pencils on a full charge. It also allows for use while charging. The USB cable ensures charging anywhere (power bank, laptop, etc.). 3 Sharpening Levels for Multiple Occasions: This sharpener features upgraded tip adjustment parts allowing for 3 sharpening levels (sharp, medium, and blunt). Choose the right level for your needs. Sharpening Available for Short Pencils: With regular sharpeners, you must hold the pencil, making short pencils difficult to sharpen. Thanks to the pencil gripping parts, our sharpener can handle pencils as short as 2.5 inches. Get the most out of your pencils before discarding them.
