Explanation:
Originally made from natural rubber, but now usually from cheaper SBR, this type contains mineral fillers and an abrasive such as pumice with a plasticizer such as vegetable oil. They are relatively hard (in order to remain attached to the pencil) and frequently coloured pink.

Explanation:
→ It is actually a mineral called graphite. which is made up of carbon. When you write with a pencil, graphite particles from the pencil rub off and stick to the fibers of the paper you're writing on.
→ when we apply the eraser on the pencil written something then it gets on eraser and it is rubbed off.
