Mitsubishi Pencil - Advance Mechanical Pencil - 0-3mm - M3 - 5591P-9
■Features a mechanism for writing beautifully.
For middle and high school students who use mechanical pencils daily for studying and other purposes, the ability to write beautifully is a highly valued function in a mechanical pencil.
The “Advance” features a mechanism for writing beautifully.
Its mechanism rotates the lead twice as fast, maintaining consistent darkness and thickness for consistently beautiful writing.
The automatic lead rotation mechanism in the “Kurutoga Standard Model,” the “Kurutoga Engine,” used a 40-tooth gear to rotate the lead once every 40 strokes. The automatic lead rotation mechanism in the “Advance” employs the “W-Speed Engine” with a 20-tooth gear that rotates twice as fast, completing one full rotation of the lead after 20 strokes. This gear modification in the automatic lead rotation mechanism enables the “Advance” to consistently produce a line width that is approximately 12% finer with HB and approximately 17% finer with 2B. (When using the same 0.5mm lead) Even with characters that have fewer strokes and longer single lines (like kana or English letters), where the lead tip tends to wear unevenly on standard non-rotating sharpeners, it can produce uniform lines.
Furthermore, when using soft leads like 2B that write darkly, it produces clear, beautiful characters without smudging, compared to conventional sharpeners.
Additionally, the mark on the automatic lead rotation mechanism inside the sharpener has been redesigned as the “W Speed Engine” mark to distinguish it clearly from the “Kurutoga Engine” mark.
Precision-machined parts suppress Kurutoga's characteristic tip vibration, ensuring stable writing feel.
The automatic lead rotation mechanism rotates the lead with each stroke, causing the gears to move up and down whenever the lead tip lifts from the paper. By using a precision-machined metal ferrule as one of the tip components, vibration is suppressed, resulting in a stable writing feel.
The built-in lead breakage prevention mechanism makes the lead less prone to breaking, allowing for focused writing. The slide pipe enables writing without extending the lead tip from the tip pipe, preventing lead breakage during writing. Thanks to its optimized shape and machining, the slide pipe allows writing without compromising the writing feel, even when the lead tip is not extended. The slide pipe moves in tandem with the lead, allowing continuous writing for extended periods with a single click until the pipe shortens. This makes it ideal for scenarios requiring sustained focus, like exams or lectures.
