The Uni Kuru Toga mechanical pencil and its new mechanism solve a serious problem for every mechanical pencil user. When you write using a regular mechanical pencil, the lead only wears down on one side, becoming a slanted, wedge-shaped tip. This will cause a terrible feeling when writing or drawing, and variations in line thickness on your paper.
The Uni Kuru Toga mechanical pencil brings a revolutionary solution to this problem. With the "Lead Rotation" mechanism inside, the pencil sharpens the lead by continually rotating it every time you lift the tip from the paper. Thus, the lead is kept in a conical tip shape that provides smooth writing or drawing and consistent lines on your paper.
