A rubber eraser is a small tool used to remove pencil marks from paper. Made from rubber or a similar material, it works by lifting graphite off the surface of the paper. Erasers come in various shapes and sizes, including rectangular, cylindrical, and novelty designs, making them easy to handle and use. In addition to traditional rubber erasers, there are also vinyl erasers and kneaded erasers. Vinyl erasers are firmer and can erase more cleanly, while kneaded erasers can be shaped to fit specific areas. These tools are essential for students, artists, and anyone who writes or draws.
