The rubber with thick heads can erase large areas, while the rubber with thin heads can erase small areas and delicate details. The thick head part refers to the structure of "lipstick", and the reserve eraser can be rotated out. The transparent color bar of the pen body can observe the margin of the eraser, thus solving the problems that the eraser is easy to lose and corrode other stationery. The suit contains a sharp replacement. When replacing, the rubber can be directly pressed and clamped.
