An eraser is a tool used to remove pencil marks from paper. Erasers come in various shapes, sizes, and materials, including:
1. Rubber Erasers: The most common type, made from rubber or a rubber-like material, which can effectively remove pencil marks.
2. Plastic Erasers: These are often found on the ends of pencils and can be used to erase pencil marks as well.
3. Vinyl Erasers: Similar to rubber erasers, but made from vinyl, which is a type of plastic.
4. Kneaded Erasers: These are soft and can be molded into different shapes. They are good for detailed erasing and can pick up pencil lead that regular erasers might miss.
5. Pencil Erasers: Often found on the ends of mechanical pencils, these are small and can be easily carried around.
6. Eraser Blocks: These are large blocks of eraser material, often used in schools and offices for cleaning large areas of paper.
7. Magic Erasers: These are a type of cleaning pad that can also remove pencil marks, but they are primarily used for cleaning purposes.
Erasers work by absorbing or dissolving the graphite or colored pencil lead from the paper, thus removing the mark. It's important to use an eraser gently to avoid damaging the paper or leaving behind smudges.
