Iwako has been making erasers in Japan for over 40 years. Each eraser is designed and its mold made, by skilled craftsmen. Every Iwako eraser is hand finished and assembled in Iwako's factory in Japan. Their erasers are like little puzzles and can be taken apart and put back together again. Excess material from the molding process is recycled to make more erasers. Iwakos products are lead and phthalate free and made with recyclable non-PVC material.
