Do you have such trouble? During the writing process, when I always use posture to write, the pencil lead will become more and more skewed, and the characters will become thicker and thicker. In order to achieve a neat writing effect, the writing posture must be changed frequently. The UNI M5-559 Rotating Mechanical Pencil solves this problem. 2x rotation, write pause once, rotate once. When writing with this pen, the pen core will automatically rotate during the writing process to achieve smoothness of the pen core, and the handwriting will not become thicker and thicker. The previous generation of KURU TOGA rotating pencils rotate every 9 °, such as M5-452. This KURU TOGA ADVANCE pencil is more sensitive with each rotation of 18 °, and the written text is clearer and cleaner. There are 3 gears inside the pencil, and the intermediate gear is connected to the lead. Through writing, longitudinal movement and pen pressure generated during the oblique meshing with the other two gears, each time the pen core of the intermediate gear falls to drive the pen tip to rotate slightly. Each stroke rotates about 18 °, and 20 strokes complete one rotation. PS: The working principle of KURU TOGA is that every time you pause writing, the pen tip will leave the paper surface and the wire will rotate once. Say it won't turn unless there is no pause during writing and the pressure on the pen is too light.
