Westcott's X-Ray Pencil Sharpeners were developed with a transparent design that makes sharpening fun! The battery operated pencil sharpener's durable stainless steel blade quickly sharpens standard size pencils to the finest point. The easy-view shavings reservoir makes it fun and easy to see when it's time to remove the shavings. The compact design makes it easy to keep on the desk, in a locker or in a backpack. This pencil sharpener operates on two AA batteries (which are sold separately).
