Bandai's "HyperCluster Pad Type Core" released February 11, 2011.
The HyperCluster Pad Type Core, along with the Star Core, were among the first base components released in the HyperCluster series.
The HyperCluster series took the ease of yo-yo customization to a whole new level. The back of the package shows you other configurations you could build using compatible bodies, core parts, and bearings from other HyperCluster-series yo-yos.
Came with the two core pieces, axle, user guide, customization guide, and trick guide.
