SHARP GLOW ILLUMINATION – The ring around the sharpener’s face lights up once the pencil is sharpened to a point. This allows the student as well as the teacher (who may not be closeby) to know that the pencil is ready for use!
TOOL-FREE REMOVEABLE CUTTER CARTRIDGE for fast and easy cleaning or replacement. Never replace your sharpener. Just change out the blade if it gets dull. Check out our video for details.
10X LONGER CUTTER LIFE – The SharpGlow has an extra hardened helical cutter developed by Bostitch Engineers that allows for longer life without dulling.
COLORED PENCIL COMPATIBLE – Lot of sharpeners make this claim but only we can back it up. Colored pencils have a bit of wax in them that can get caught up in the blade of any sharpener. But since this electric pencil sharpener has a blade that you can access, simply remove the blade and wipe clean. It’s that easy.
ANTIMICROBIAL PROTECTED – We know that germs and classrooms go hand in hand. That’s why we developed our classroom sharpener with antimicrobial protection
QUIET MECHANISM – We don’t call it the QuietPro 6 for nothing. Developed to keep you running an efficient and focused classroom, even when there is a long line at the sharpener.
STALL-FREE MOTOR - super duty motor with thermal overload protection keep the plug in sharpener from overheating. Sharpen a high volume of pencils back-to-back without a break.
TAMPER-PROOF SAFETY SWITCH – This shuts down the motor when large shavings bin is removed. This is the Bostitch standard for safety in a classroom environment.
TRUSTED BOSTITCH WARRANTY – Our warranty is 7 years and back by a brand you can trust.
