The Kuru Toga Advance features an automatic lead-rotation mechanism designed to keep line darkness and thickness consistent while writing. Its W Speed Engine rotates the lead once every 20 strokes.
Features
A precision-machined metal tip component helps reduce vibration for a steadier writing feel.
A sliding pipe lets you write without exposing the lead beyond the tip, helping reduce lead breakage. This feature works only while the lead is not extended beyond the tip.
The sliding pipe moves with the lead, allowing continued writing after one knock until the pipe shortens.
