This is the yoyorecreation plastic yo-yo "Diffusion." It's a bind-response yo-yo. There are molding marks typical of plastic and a slight wobble that doesn't seem to affect play. Product Specifications: Weight: 65.1 g Diameter: 57.8 mm Width: 43.1 mm Body Material: Polycarbonate/ABS, etc. Response: IrPad YYR Large Bearing: C-size bearing A thin bearing that allows for a responsive return should have been included, but I couldn't find it, so this is the main body and box only. A string is not included, but please let me know if you need one after purchase. If you're looking for an easy-to-play plastic yo-yo, how about this one? Please understand that this is a used item before purchasing. #Yo-yo listings are here
