This final run of the Catalyst are 100% made in the USA, and are sandblasted on the rim with the inner bowl remaining polished – just like the most popular original YYF throws. These come equipped with Z-stacks for ultimate hubstack play, but optimal smoothness is reachable with either regular stacks (included) or nubs. Many team players feel the Catalyst Stacked with nubs is their favorite competition throw.
Four colors available in this one-time run, limited quantities.
Vinyl Nubs (optional) to cover the hubstack post, play without stacks or outside bearings - can be found here: http://yoyoloco.com/products/nubs-for-hubstack-post
*** For Advanced/Expert players, this an non-responsive yo-yo capable of extremely long spin times. You will need to perform a "bind return" in order to make this yoyo return to your hand.
