Uni Kuru Toga Mechanical Pencil
There's a real problem that affects almost all mechanical pencils—bear with us as we explain. As you use a regular mechanical pencil, the lead wears down on one side, forming a slanted wedge-shaped tip. This can cause dramatic and unsightly variations in line thickness as you write or draw. The Kuru Toga eliminates this problem with the use of an ingenious lead rotation mechanism that continually rotates the pencil lead as you write.
