Pentel Orenz 10th Anniversary Limited Edition Mechanical Pencil

Brand: Pentel

Model Number: XPP503 (0.3mm), XPP505 (0.5mm)

Lead Size: 0.3mm, 0.5mm

Functionality: Revolutionary Orenz Anti-Break System with sliding guide pipe, single-click lead advancement mechanism, and fully retractable sleeve for safe pocket storage.

Best For: Ultra-fine writing, complex math equations, detailed sketching, small-print note-taking, and writers prone to heavy lead breakage.

The Pentel Orenz is an innovative mechanical pencil designed to solve lead breakage, even when using ultra-fine leads. Utilizing Pentel's proprietary sliding sleeve system, the lead is completely shielded by the smooth metal guide pipe as you write, allowing the sleeve to slide back automatically as the lead wears down. With its one-click mechanism, you only need to press the top once to expose the guide pipe without extending the lead past the metal edge—ensuring clean, break-free, and smudge-resistant lines.
