The MF8 Legend 3x3 is the first version of MF8's Legend 3x3 series and features one of a kind internal design. The pieces on this cube are very unique due to its special ball core. The turning on the MF8 Legend is extremely fast and has a nice smooth feel to it. As one of the most classic examples of innovation in 3x3 core design, the MF8 Legend 3x3 is a must-have for collectors and speedcubers alike. For the best performance, we recommend keeping the screws tighter.
