Japan UNI KURA TOGA Mechanical Pencil 0.5mm Automatic Rotation Drawing Special Pencil M5-559 Stationery Cute School Supplies

Keep the pen core thickness and reduce the core break rate：It only rotates automatically when the pen core becomes dull, and does not rotate when the pen core is sharp.

​PS:
​The working principle of KURA ﾠ TOGA is that when the writing pauses, the pen tip leaves the paper, and the lead rotates once. It is not in the non-stop writing. The lead rotates continuously; the one that does not rotate is not paused during the writing And the pressure pen is too light.
​The secret of constant core
​The front part of the refill can be written without being exposed. The edge of the library tube is smooth, the writing is smooth, the pen tube protects the lead, and the writing is continuous.
​Anti-break premise: the lead core needs to be in the protection of the pen tube
