Pentel Orenz Mechanical Pencil Auto Lead 0.3mm XPP503 / 0.5mm XPP505 Limited Edition

This Orenz mechanical pencil from Pentel has an ultra-fine 0.3mm lead - perfect for creating fine, detailed work. Ideal for architects, engineers, designers and illustrators, the pencil has a unique 'one-click' mechanism to advance just the right amount of both the lead and the protective sleeve, and a superior clutch mechanism protects the lead even further. This mechanical pencil features 0.3mm lead for amazingly thin, clean lines. It's great for writing notes, math problems, graphs, and more!

Despite being so fine, the lead doesn't break as you write, due to the innovative Orenz mechanism. The guide pipe protects the entire length of the lead, and you write without extending the lead out of the guide pipe, which glides right along the surface of the paper. Since it has rounded edges, the guide pipe doesn't catch on the paper or scratch it. As you write, the guide pipe gets shorter. When you need more lead, just click the top button as you would with any other mechanical pencil. The guide pipe will extend again, along with the lead inside.

Because there's no lead breakage, your papers remain clean without smudges from broken lead dust. You can also retract the guide pipe so it doesn't poke you or your belongings when you've stowed the pencil away.
