Ultra quiet and break resistant, the X-ACTO Quiet Pro Electric Pencil Sharpener provides less breakage and less noise for less frustrations and distractions. With the SmartStop feature, the pencil sharpener prevents over-sharpening by automatically shutting off the electric motor when the pencil reaches ideal sharpness. Meanwhile, a bold LED light lets you know when the sharpening is complete. The auto-adjust dial works with nearly all pencil sizes while the slip-resistant bottom keeps the pencil sharpener steady. Finally, the SafeStart electric motor stops when the extra-large, easy-to-empty shavings bin is removed. It's also compatible with colored pencils. Stay sharp with X-ACTO, the #1 electric pencil sharpener brand!
