The QuietSharp Glow provides the ultimate blend of performance, safety, and style for the classroom or studio. To make each pencil last a little longer and reduce classroom disturbing noise, the SharpStop system automatically shuts the sharpener down once the pencil is completely sharp. Then the unique SharpGlow light will come on, creating a soft blue glow around the dial to provide a visual indicator to the student and the teacher, who may not be close by. Its 6-size selector dial is perfect for a variety of pencils. Whether your classroom is full of elementary school students using a jumbo pencil or a Ticonderoga Tri-Write; or older learners who use standard pencils, this electric pencil sharpener has got you covered! And for ease of use, the Tip Saver Technology prevents over sharpening, extending pencil life. Once a pencil is completely sharp, the blade cutters will pull back and no further sharpening can be done. The XHC cutter technology allows for 70% faster sharpening and 10x longer life. It is made with extra hardened steel and the blade is designed to be helical, allowing for a pointed tip every time in under 4 seconds. With the combination of a super duty motor and thermal overload protection, this electronic sharpener is completely protected from overheating. This means you can sharpen a lot of pencils without having to take a break in between. The operation is quiet with the durability to withstand strenuous classroom use. The giant shavings tray features our patented MagnaSafe tamper proof safety switch which shuts down the motor when the tray isn’t attached. So, if the tray is removed, there’s no way to get the motor to run. This makes it the standard for safety in a classroom environment with young children around. The unique curved shape and sleek brushed metal case offers class-leading style and classroom survivability. Antimicrobial properties built-in to protect the product with Agion® silver ion-based agent. Agion® is a registered trademark of Sciessent®.
