Using the Zoomarang is a breeze. First, hold the boomerang by its edge with a firm grip. Stand with your feet shoulder - width apart and face in the direction you want to throw. Swing your arm forward in a smooth motion to send the boomerang out. It should circle out about 10 metres and come back to you. The included throwing instructions can teach you more advanced tricks. As for age, it's great for kids 4 and up. When throwing, make sure you're in a safe open area like a yard, park, beach, or playground. Regarding the styles, be aware that they are randomly selected at dispatch. If you have a preference, add a note to your order. After use, just store it in a dry place to keep it in good condition. And remember, each Zoomarang is sold separately.
