Suitable for beginners and advanced players! Inside there is a game manual. Made of high quality polycarbonate plastic. This is a great way to increase physical activity for children and their parents! How do I use Yo Yo? The thumb is dipped into the loop and the other fingers hold the string. Then the disc is started, which spins as it falls and unwinds the string. When the disc reaches the lowest point, it continues to rotate due to inertia and starts to wind the string again, and as it winds up, it rises again. Pulling the holder at the right moment accelerates the upward movement of the disc, causing the string to wind back up to the position it was in before the disc fell, only in the opposite direction. The disc then falls back down and the cycle repeats. Recommended age: 8+ Caution! Not suitable for children under 3 years. Do not throw near people, animals or breakable objects. Made in China to special order from YoYoFactory, United States of America.
