Say goodbye to dullness and frequent lead breakage with the engineered design of the uni-ball KuruToga Mechanical Pencil. This mechanical pencil features a unique rotating lead mechanism that prevents the lead from breaking and maintains a continuous sharp point. ​Easy Placement - ​​The pencil continues to rotate and sharpen the lead as you write. Unlike regular mechanical pencils, which produce thicker, lighter lines after a few uses, Kuru Toga Fancy Mechanical Pencils stay sharp so they produce the same thin, dark lines you started with, making your handwriting clearer ,more accurate. Even better, KuruToga contains exclusive diamond infused lead. It not only enhances your writing experience but also creates dark and vivid lines. ​
