uni KURU TOGA Mechanical Pencil 0.5mm

• When writing, the rotating wheel drives the refill to rotate, so that the angle of the refill is consistent and maintains a conical shape
• Let the refill maintain the same shape every time it touches the paper, so the thickness of the written font line can be consistent
• It will not allow the extremely thinned refill to directly contact the paper surface to grind out excess graphite powder.
