Advance maintains the conical shape of the lead, ensuring uniform wear and consistent density and thickness of lines, even with continuous writing. This feature allows for nice clean notes throughout.
Double-Speed Engine fully rotates the lead every 20 strokes, half as many as the conventional Kuru Toga. This enhancement for faster rotation ensures finer, more consistent lines for crisp writing and precise drafting.
Advance is perfect for fast note-taking, thanks to its "lead protection mechanism," which features a retracting slide pipe. This eliminates the need to extend the lead from the tip, preventing lead breakage while writing.
The precision-processed metal grip with fine perforations offers a luxurious feel and finger guidance for writing, complemented by a barrel with a smooth, pleasant finish for enhanced grip comfort.
Advance Upgrade features an exclusive metal grip that creates a stable low-center-of-gravity. Its mechanism is intentionally concealed, instead emphasizing a barrel design that combines sleekness, stability, and ergonomics for comfortable writing.
