Using your Duncan Indoor Boomerang is a breeze. First, hold the boomerang firmly with your fingers along the edges. Then, give it a good, smooth throw indoors within the 15 - 20 feet range. If you want to change how it flies, you can 'tune' it by adjusting its shape a bit. When it comes to catching, just keep your eyes on it and reach out your hands at the right time. As for maintenance, since it's made of soft foam, keep it away from sharp objects that could tear it. And when you're done playing, store it in a cool, dry place. Remember, this is an assorted item, so the style you get might be random. If you have a preference, let us know in your order notes. Also, it's meant for kids aged 6 and above, so make sure younger kids are supervised if they want to play with it.
