The Son-Mum Cube is a 3x3 mixup cube designed by Mike Ambrust and produced by mf8. It features a 3x3 outer edge with a smaller 3x3 located on the inside of each cube face. As is common with most mixup style cubes, it is possible to scramble the inner 3x3 along with the outer 3x3 at certain positions, which allows the puzzle to be scrambled in some unconventional manners. It displays both the Mike Ambrust and official mf8 logo.
Dimensions: 6.6 cm x 6.6 cm x 6.6 cm / 2.6 in x 2.6 in x 2.6 in
