Uni Kuru Toga Advance Mechanical Pencil - 0.5 mm - Blue

The Kuru Toga Series from Uni-ball Mitsubishi has a core rotation mechanism that can automatically rotate the pencil lead as you write. The lead is twisted through a spring-loaded clutch, it works by twisting incrementally every time you lift the pencil up (i.e. during printing words, etc.). This allows a uniform wearing of the pencil lead so that it always remains as a pointed tip.
