In daily life and work, as a correction tool, the material and quality of an eraser are directly related to the user experience and effectiveness. When selecting a suitable eraser, it is necessary to consider not only the material but also the quality and use scenario. The following are some suggestions for choosing the material and quality of an eraser. Firstly, regarding the material of an eraser: Natural rubber: It is the main material for traditional erasers, with good erasing effect and durability. This type of eraser is suitable for most scenarios, especially for students and office workers. Synthetic rubber: Synthetic rubber erasers have improved hardness, elasticity, and durability, especially suitable for erasing difficult-to-remove traces. Soft erasers: This type of eraser is made of soft material and is not easy to damage paper or painting surfaces. It is suitable for fine drawing or correction work.

Environmental friendliness: Consider choosing an eraser made of recyclable or environmentally friendly materials to reduce environmental impact.
