Here’s a cute 34 piece set of Iwako Japanese erasers on Amazon. It includes 6 frogs, 3 puppies, 11 hamsters, 7 pandas, 7 marine animals, and 3 duck erasers. There are several colors for each animal and 34 animals total.
You can play with them and trade them with your friends at school. Other kids will trade other cool things just to have one of these cuties.
Or you could hand them out in birthday gift bags.
