We want you to pick out just the right boomerang for your youngster. We recommend softer material boomerangs like pliable plastic and foam for kids ages 5 to 7 or higher. Nothing with sharp corners or harder materials. These boomerangs are also lighter and smaller than what you might anticipate. Remember, they are designed to be small enough and light enough for young arms. Also always remember parent supervision is needed for children with boomerangs.
