1. Quick Lead Release
The center window gap functions as a lead trigger release. This will greatly increase the speed of releasing pencil lead. It is the fastest lead release on any lead holder.
2. Lead Usage Window
Most 2mm leads have labels printed on it. PENXO is designed to intuitively display those labels, as well as color and usage, without needing to unload the lead or use spinning knob indicators commonly found on drafting pencils.
From 4H to 4B to color leads, it will take any 2mm lead of your choice and also protects the lead securely when not in use.
