Extended information:
The words written with a pencil and the words written with a pen must be erased with different erasers. According to the different pens, writing with a pencil only remains on the surface of the paper, and does not go deep into the paper. The pen book will soak into the fiber of the paper and dye the paper ink. When you use an eraser to erase the handwriting of a pencil, it is actually the eraser that absorbs the handwriting written by the pencil on the paper.
when writing with a pen, if you want to erase the writing on the surface of the paper and the inside of the paper that is slightly deeper, you have to mix hard fine powder into the eraser. This kind of eraser works just like filing things with a file, but wiping off the traces of pencils with an eraser is a phenomenon caused by friction.
