The eraser is made of PVC material, but the plasticizer ATBC is added. That is, using physical principles (non-magic pen) to peel off the handwriting (not only pencil characters) from the surface of the written object (excluding correction tape and correction fluid).


When using an eraser to erase the writing of a pencil, it is actually the eraser that absorbs the handwriting (made of pencil powder) written on the paper with the pencil. Just use an eraser to erase the pencil writing along the "footprint" of the eraser, that is, the adsorption force of the eraser on the pencil powder is greater than the adsorption force of the paper on the pencil powder. When writing with a pen, if you want to wipe off the writing on the surface of the paper and the inside of the slightly darker paper (ink that enters the paper), a hard fine powder must be added to the eraser. The working principle of this kind of eraser is like filing something with a file, but using the eraser to erase the pencil marks is a phenomenon caused by friction.
