Pentel Orenz AT Mechanical Pencil, Dual Grip Type, 0.5mm

Introducing a new model of Orenz, featuring an "automatic lead advance mechanism" that lets you keep writing with just one knock, the "Orenz System" that protects the lead with a pipe at the tip of the pen, and a "dual grip" that allows for a firm hold, allowing you to concentrate more than ever before and keep thinking.

Low center of gravity makes writing less tiring even for long periods of time
The pen is equipped with an automatic lead-out mechanism that automatically advances the lead each time the pen tip leaves the paper. With just one knock, you can keep writing until the remaining lead becomes short.
In addition, it is equipped with the "Orenz System" that protects the lead with the pen tip so that it won't break. The pipe at the tip of the pen slides according to how much lead is left. The pipe protects the lead so you can continue writing without breaking it.
