Dual purpose sharpener & eraser in one convenient case. On one side a soft synthetic rubber eraser perfect for removing most graphite pencil marks.
The other side is a sharpener made of carbon steel which is impact and wear resistant ensuring a sharp blade. The sharpener blades are secured with a safety blade to prevent accidental human contact making it ideal for school use.
The shavings are conveniently caught in a receptical so they can be thrown in the trash instead of the classroom floor.
Can be used with graphite & coloured pencils alike.
