They say good things come in small packages, and that's true of Custom's Reactor yo-yo. This undersized aluminum ball-bearing transaxle yo-yo uses a positive grip system for a response that's amazing (especially given its smaller size) and the heavier weight and ball-bearing ensure that it gives good, long sleepers. If you're looking to experiment with a smaller yo-yo, this is a good first -- or last -- choice. Because we receive so many different colors of this yo-yo in such small quantities we cannot offer a color choice. However if you'd like to request a color, your more than welcome to. In 2008 Custom changed their bearing size to A. If you have an older Custom yo-yo you may need the old I bearing size.
