From the yoyoplay.com website:
"The Yoyo Factory Boss yoyo is an undersized unresponsive yoyo. It’s made from smooth metal, making for nice grind surfaces.
For an undersized yoyo, this is an affordable, stable yoyo that’s great for on-the-go! Want a yoyo that’s easy to fit in your jeans pocket, but performance is not limited to its small size? The Yoyo Factory Boss is it. The size doesn’t impact long spin times or stability.
The Yoyo Factory Boss is an unresponsive yoyo. You’ll need to know how to perform a bind to return the yoyo to your hand. A bind is when you wind string into the gap of a spinning yoyo, forcing it to grab the string and come back up toward your hand.
Not only does the Yoyo Factory Boss make a great travel yoyo with its compact size. It’s also a great beginner yoyo for people or kids with smaller hands ready for an unresponsive yoyo."
