Just like the original Nerf Ball first introduced in the 70’s, this World’s Smallest Official Nerf measures only 1.25" in diameter and is made of the same soft, durable foam. Comes packaged in it's own 1.25" square carrying case with keyring so you can take it everywhere . Great for "wastebasketball", "sock soccer", "Nerfminton" and playing with the pets, it’s perfect for Nerf fans of all ages! Included is 1 ball, 1 case and 1 keychain. Not recommended for children 3 and under due to tiny parts!
