8. The difference between 2B and 4B erasers:
2B and 4B are two common eraser hardnesses, and there are some differences between them.
First of all, the 2B eraser is relatively harder than the 4B eraser. This means that the 2B eraser is better at erasing light pencil lines, but may not be as effective at dark pencil lines. In contrast, the 4B eraser is more suitable for erasing dark pencil lines but may leave marks on light lines.
Secondly, the 2B eraser is usually better for detail erasing than the 4B eraser. Because the 2B eraser is relatively hard, it can erase small details, such as lines around the eyes or mouth, more accurately. In comparison, the 4B eraser may be too soft and difficult to erase details accurately.
