Seed Kneadable Eraser

Kneaded erasers are good for tasks harder erasers can't handle, like wiping up charcoal, pastel, and colored pencil. They can be molded into any shape and rubbed gently against the paper to create lighter values within dark areas. And they clean themselves; just stretch and knead the eraser until it gets lighter in color.

It's a soft, effective eraser made of white synthetic rubber, and it's generously sized, unlike many other brands.
