uni Kuru Toga Advance - Auto Lead Rotating Mechanical Pencil, 0.5mm (Navy) - Mitsubishi Pencil, M5-5591P.9

• The Kuru Toga Advance has a core rotation mechanism that continually rotates the pencil lead as you write. A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper, allowing a uniform wearing of the lead so that it always remains pointed. The new W-Speed engine turns lead twice as fast as the original uni Kuru Toga for continuous sharpening. Every 20 strokes, the lead turns thereby always keeping the tip sharp and precise. The metal pipe at the tip keeps the lead from breaking and retracts as you write ensuring the perfect amount of lead is always exposed. The Nano Dia lead is infused with millions of nanodiamond particles and silicone oil, resulting in a strong lead that produces darker and smoother lines.
