Pentel Orenz AT Japan Version Mechanical Pencil (0.5 mm)

Featuring the same auto-advancing lead technology as the Orenz Nero, the Orenz AT lets you write for page after page without interrupting your flow to extend the lead. Every time you lift the lead from the paper, it advances a little bit of lead. Once the lead becomes too short, it will extend back to its original length. The pencil's metal grip section is studded with rubber pads, providing a comfortable balance of weight and grippiness. And like all Orenz pencils, the AT features a sliding lead sleeve that makes it almost impossible to break the lead. You can retract the lead sleeve so that it doesn't poke you or your belongings when you've stowed the pencil away.
