Perfect pencil idea design

The "CASTELL Perfect Pencil" It's no mean achievement to pack to much into a small space as the Perfect Pencil does. The extender protects the point from breakage, while the robust clip stows the pencil away neatly in a pocket with no risks of damage to either. When you pull out the knob at the end, it reveals a sharpener. Add to that the eraser on the end of the pencil, and you have all you need in the handiest possible form.
