Clamp Principle

The forward cutting gap on PENXO's tip creates a pivot tension at the opposite end. This counter balance creates a clamp-like effect, providing pressure on the front tip, which secures the lead in place and prevents it from sliding out.



How To Use 

Slide in any 2mm lead.

Push your thumb between the Lead Window Gap for quick lead release.

Apply light pressure on grip while writing. 

Easy monitoring of lead color, usage and hardness labels.
