| 塑膠球軸心 The axle of plastic yo-yo. |
我們悠九做得就是不一樣，即便是塑膠溜溜球我們一樣可以使用獨家的軸心系統，不像市面上的廠商他們的塑膠球設計幾乎都一樣。這再次證明了我們是真的有在用心設計的。
We always make the different. We use the Exclusive Axle System even design the plastic yo-yo. Other plastic yo-yos in market almost are the same design of bearing and axle. This improves that we are surely DESIGN a yo-yo again.
