Introducing the Duncan Pro Z™ with MOD Spacers™ Yo-Yo! A new addition to Duncan's Hardcore Series of yo-yos, Pro Z features patent pending shape changing spacers that allow you to modify the shape converting it from a standard looping style yo-yo, to a wide body string trick yo-yo!

The Pro Z (played WITHOUT the spacers) is designed for basic to intermediate sleeping tricks such as walk the dog & rock the baby to looping tricks such as loop the loop and hop the fence. Pro Z makes these tricks easy to perform with its high speed ball bearing axle for long spin times, and starburst response system for quick returns.

By installing the included MOD Spacers, you can turn the yo-yo from a narrow body beginner-intermediate yo-yo, to a wide body high performance yo-yo! The included MOD spacers feature a recessed response system that allows for difficult string tricks to be performed without snagging or losing spin time!
