Features: Unresponsive Yoyo: The black peal is an unresponsive yoyo, using an unresponsive bearing. You need to perform tricks to make it return. Perfect for more advanced 'sleeper' tricks. Excellent Performance Yoyo: Made of 6061 alloy aluminum by CNC numerical control lathe, anti-corrosion, stable and robust, you can play yo-yo string tricks very well. It's a professional yo-yo. Anodizing surface treatment makes this professional yoyo ball never fade and not easily scratched. It is a good intermediate yoyo. Undersized Yoyo: Diameter: 52MM. Width: 40.16MM. Axle width: 4.45MM, perfect for daily use. But it is quite heavy for the size, due to how rim-weighted it is. This makes it very stable and comfortable to play with. Slightly heavier weight gave the yo-yo good balance and longer spin time too. Nice and Fun Gift: THIS yo yo toy is an ideal gift for your kids and friends. It is fun and educational. TIPS: This is an unresponsive yo yo, which means you need to do some tricks to get it back to your hand. It will not return automatically like a responsive yoyo. Age: For ages 8 and up. The yo-yo string should be replaced regularly when the yo-yo string becomes defective, it helps you play better.
