Sketch like a professional with this kneadable eraser from Hot Cool Tokyo.

This pliable eraser can be stretched, molded, and compressed into any shape your erasing heart desires. Instead of shedding itself as it erases, kneadable erasers absorb the charcoal or graphite they lift from the page. They are ideal for erasing small mistakes on  fine paper that you don't want to damage with hard rubbing - just press (don't rub) onto your mistake and voilà! No more mistake.
