The YoYo Factory One is a superb, great value beginner's string trick yo yo.
This is the beginners pack for the YYF one, coming with a responsive bearing installed by standard, and with a ready to use loop tied so you can get throwing immediately. once you're through with that string, though, don't worry. there's a spare.
This version of the one does not come with an upgradeable unresponsive bearing, but can be upgraded just as easily by getting one of the yoyofactory centertrac bearings here
The One has a comfortable, classic butterfly shape and is equipped with silicone response pads. For more details, check the specs tab.
