This latest version of the legendary SB2 (SB2.2)yo-yo is computer engraved with it's own serial number and polished to bring out the brilliance and lustre of the high tensile aluminium alloy. It comes complete with an illustrated 40 page flight manual, turbo discs for improved control and performance, leather holster, weights, and 5 extra pro grade strings. This yo-yo can be custom tuned to your preference by adding weights or adjusting the string gap.
