Many students wonder whether to choose a 2B or 4B eraser for exams. The answer depends on the task at hand, as these two types serve different purposes.

2B erasers are firmer and more precise. They are designed for standard pencil writing and produce minimal residue. For exam scenarios, especially when using standardized test answer sheets, a 2B eraser is recommended because it erases cleanly without damaging the paper surface. The firmer texture allows for controlled, accurate erasing of individual answers without affecting surrounding marks.

4B erasers are softer and more pliable. They are ideal for artistic work, such as sketching and shading, where larger areas need to be modified. The softer material provides better grip on graphite particles, making it effective for removing darker pencil marks and creating highlights in drawings.

For exam use, the key criteria are: erasing cleanly without leaving smudges, not tearing the paper, and producing crumbs that are easy to brush away. A high-quality 2B-style eraser from a reliable manufacturer will meet all these requirements.

Zhejiang Qihao Stationery Co., Ltd. manufactures exam-grade erasers specifically designed for standardised tests. Using premium TPR material, Qihao erasers have an exceptional erasure rate that exceeds national standards.
