mf8 Constrained Megaminx
The mf8 Constrained Megaminx is as a stickerless megaminx that is the same size as the mf8 Gigaminx and mf8’s other 9cm dodecahedron puzzles. Each side has a lock mechanism that constrains (or limits) the movement of the side, making it more difficult to solve than a normal megaminx puzzle.
The puzzle also comes with 2 sets of tighter or looser constraints, which can be swapped out to make the puzzle more or less difficult, respectively.
The Black version comes unstickered with a set of stickers on the side.
