The Gung-Fu Gen 2 is the latest version of James Copley's hand dyed delrin yo-yo. This small form yo-yo is smooth and fast on the string. Comes with a pre-cleaned ABEC 5 bearing so it comes stock out of the package unresponsive. It uses O-Stickers for a consistent and easy to replace response system. This is a yo yo with serious play without the serious price tag. We here at II all have one of these in our collection.
