We often lost the top lid of mechanical pencil when we need to refill the pencil or use the tiny rubber on the back.
"Eraser Cap" is a mechanical pencil lid made of eraser,
With this design, we don't have to remove the lid,and just use the top to erase.
Moreover,this way improves the problem that the eraser is too tiny to be pulled out.
You just need to change a new " Eraser Cap " without buying a new mechanical pencil, which is cost effective and conventient.
