• 【Hurricane Speed-Sharpen Well in 1 Second】This electric pencil sharpener sharpens incredibly quickly: 1s for a dull pencil, 2.5s for new, which is nigh impossible for any other sharpener on the market! Great for 6.5-8mm graphite, colored, hard charcoal, #2 pencils. Insert a pencil inwards GENTLY(≤25Newtons) and HORIZONTALLY(for a even tip), and it comes out super sharp and balanced! Please don’t push the pencil too hard when sharpening, or it will make “hum” noise and not sharpen pencil.
• 【Consecutively Sharpen 50 Pencils】The pencil sharpener fast sharpens 50 pencils without intervals. Pretty darn durable and powerful to be heavily used for those who’re constantly drawing and resharpening all day, no problems show so you don’t have to care as much thanks to the heavy-duty S.S. helical blade that makes this electric sharpener a beast every time it sharpens! Tremendously save time, labour, and money on endless trials and errors on many of others, clunky and weak to use.
• 【Auto Stop and Save Pencils】The automatic pencil sharpener will auto stop when it “senses” the pencil is pointy so as to prevent over sharpening and eating pencils. A sharpener that actually sharpens pencils fast, completely and “intelligently”, you’ll never regret having stumbled upon such a colored pencil sharpener ever. Amid sharpening, you can even hear and feel the power the heavy-duty motor has. A necessity for teachers, artists, kids for distance learning, homeschooling, etc.

Maybe a few bucks more, but time will tell you it’s worth every penny if you want one that lasts. Weighed well and designed with non-skid pads in the bottom, it won’t slip around while sharpening.
• 【Safety Design】Two safety features in design: The blade won’t work when reservoir is removed or not in proper position(child friendliness); If the electric pencil sharpeners overheat after numerous uses it will automatically stop working to protect itself, please wait for about 10mins to let it cool down before rebooting. Plug in pencil sharpener requires no battery installation and consumption. Large reservoir has drawer-type opening, barely needs emptying, but easy to be emptied if needed.
