Double-sided Eraser / Blackboard Eraser

Double-sided Eraser
Double-sided Eraser

When we use the blackboard eraser, we are often troubled by the chalk powder. The double-sided eraser will help us in this problem. The chalk powder on one side can be shocked to the transparent shell when we use the other side to erase the board, because the steel ball in the eraser will beat the blue plastic shell when the eraser is shaken. This makes the process of erasing clean and convenient.
