7. Are exam erasers more expensive?

Generally speaking, the price of exam erasers may be slightly higher than that of ordinary erasers. This is because exam erasers are often specially designed to ensure more effective erasing of pencil marks and less damage to the paper in an exam environment. However, the exact difference in price may vary based on brand, material, and performance.

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.

The exam eraser is an indispensable tool for students during the exam. It can help us correct mistakes and improve the neatness and readability of answers. By choosing the eraser that suits us, using it correctly, and maintaining it, we can make better use of the exam eraser to improve exam results. During exams, let the exam eraser become our right-hand assistant, adding convenience and confidence to our academic journey.
