The Uni Kuru Toga mechanical pencil and its new mechanism solves a serious problem for every mechanical pencil user. When you write by 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 you are writing or drawing and variations in line thickness on your paper.
The Uni Kuru Toga mechanical pencil brings a revolutionary change for solving this problem. With the "Lead Rotation" mechanism inside, the pencil is able to sharpen the lead by continually rotating the lead every time you lift the tip from the paper. So the lead will be kept in a conical tip shape that provides a smooth writing or drawing and consistent lines on your paper.
