From series 1, the Black Mamba Regeneration 2000 Limited Edition featured a state-of-the-art ball bearing axle system, and take-apart design. Unlike other Black Mamba models, however, this version had no auto return mechanism. This smooth, long spinning yo-yo was great for all types of string tricks. What made this version a limited edition was the all black body and gold foil imprint on black side caps. This model was also made in a regular edition seen here.
