The "pencil break prevention mechanism" is effective only when the pencil does not protrude from the tip.

The ability to write beautifully is considered important and is a function required for a pencil, especially among middle and high school students who use a pencil daily for educational purposes.

The mechanism that rotates the pencil twice as fast allows you to continue writing beautifully without changing the darkness or thickness.

The automatic rotation mechanism of the "Kurutoga Engine" in the "Kurutoga Standard Model" uses a 40-tooth gear so that the pencil rotates once every 40 strokes. The automatic rotation mechanism of the "Advance" pencil is equipped with a "W Speed Engine" that uses a 20-tooth gear rotating twice as fast, allowing the pencil to rotate once every 20 strokes. By changing the gear of this automatic pencil rotation mechanism, it is now possible to continue drawing lines that are about 12% thinner with HB and about 17% thinner with 2B.

The precisely machined parts minimize the vibrations of the pen tip, unique to the Kurutoga, for a stable writing feel. The automatic pencil rotation mechanism rotates the pencil every time you write, so the gear moves up and down whenever the pencil tip is lifted off the paper. By making the cork, one of the tip's parts, a precisely machined metal piece, vibrations are reduced, and the writing feel is stable.

The pencil break prevention mechanism makes it difficult to break the pencil, allowing you to focus. The slippery tube, which allows you to write without needing to extend the pencil tip from the tip tube, prevents the pencil from breaking during writing.
