An eraser is a tool used to remove or erase pencil marks from paper. Erasers are usually made of rubber, vinyl, or soft plastic and can easily remove pencil lines without damaging the paper.

Here are some common types of erasers:

1. Rubber erasers: These are the most common type of erasers and are often found at the end of pencils. They work well for regular pencil marks.


2. Vinyl (plastic) erasers: These erasers are stronger than rubber ones and are more effective at removing darker and thicker lines. They are also useful for more precise work.


3. Kneaded erasers: Soft and flexible, these erasers can be shaped into any form and are great for erasing small details or precise areas. They are commonly used in art for sketching.


4. Electric erasers: These battery or electric-powered erasers rotate quickly to erase pencil marks faster. They are helpful for intricate designs or when working on larger.
