• Appearance: Erasers come in various shapes, sizes, and colors. The most common erasers are rectangular or cylindrical in shape, but they can also be found in fun shapes like animals, fruits, or cartoon characters, especially for children's use. The color is often white, pink, or gray, but novelty erasers can be found in a wide array of colors.

• Material: Traditionally, erasers were made from natural rubber. However, modern erasers are often made from synthetic materials like vinyl, plastic, or gum-like substances. These materials are soft and pliable, allowing them to remove pencil marks without damaging the paper.

• Texture: Erasers have a soft and slightly gritty texture. This texture is designed to pick up graphite or pencil lead from the paper's surface without tearing or smudging the paper.

• Usage: To use an eraser, you simply apply it to the pencil mark on the paper and rub gently. The friction between the eraser and the paper causes the graphite or pencil lead to stick to the eraser, effectively removing the mark. It's important to use light pressure to avoid damaging the paper.

• Size: Erasers come in various sizes, from small ones that fit on the end of a pencil to larger ones that can be held comfortably in the hand. Some erasers are designed to be attached to the end of a pencil, providing a convenient tool for erasing mistakes while writing.

• Function: The primary function of an eraser is to remove unwanted pencil marks. It is an essential tool for students, artists, architects, and anyone who uses pencils for drawing or writing.

• Variations: There are specialized erasers for different purposes. For example, kneaded erasers are popular among artists because they can be shaped into fine points for detailed erasing. Electric erasers use battery power to rotate a small eraser nub, providing precise control over erasing. Pen-style erasers resemble pens and are convenient for erasing small areas with precision.
