Uni's fabulous Kuru Toga solves a problem that affects majority of mechanical pencils. The angle of writing creates a chisel tipto the lead which affects the actual line width and tends to crumble off. Kuru Toga rotates the pencil lead as you write using only the kinetic energy created by your pencil strokes. The rotating lead results in a uniformly sharp point instead of the chisel tip which means neater lines and a stronger lead. Kuru Toga has been a sensation all over the world and is our favourite pick because of itsinnovativeness andarchival quality.
