The 4x4x4 Mixup Plus is made from a hard black plastic. The object of this puzzle is to scramble up all 6 sides and then return it back to its normal position. There is much more to this puzzle than first meets the eye, as it is actually a shape-shifter. It breaks its shape when either of the middle two rows are turned at a 45° angle (half a turn) and then rotated in a different direction. The 4x4x4 Mixup Plus is developed by WitEden who is a manufacturer and a wholesaler.
