Mitsubishi Uni Kuru Toga Advance X Japan San-X Rilakkuma Limited Edition Mechanical Pencil (0.5mm)

This Kuru Toga Advance features an updated "W Speed" mechanism, which rotates the lead twice as fast as standard Kuru Toga pencils so that the lead gets sharpened twice as quickly. Standard Kuru Toga pencils rotate the lead once every 40 strokes, while the Kuru Toga Advance rotates the lead once every 20 strokes. The Advance's mechanism also features metal parts for smoother, more reliable performance.
