mf8 Son-Mum 3×3 V1
The mf8 Son-Mum Cube is a 3×3 mixup cube designed by Mike Ambrust and produced by mf8. It features an outer 3×3 with a smaller 3×3 located on each center. As with most mixup style cubes, it is possible to scramble the inner 3×3 along with the outer 3×3 at certain irregular points, which allows the puzzle to be scrambled in some unconventional ways. It features both the Mike Ambrust and official mf8 logo.
