The scribble protector cap is a pencil sharpener that fits on the end of your pencil. It protects the end of the pencil, sharpens the pencil and extends the length of the pencil for ease of use. It will surely keep all pockets and pencil cases clean. The blades are made of high-carbon steel, therefore long-lasting and very sharp. Dynamic torsion action built into each blade makes for a smoother, cleaner cut.
