WitEden 4x4 Mixup (Edge-Split)

The WitEden 4x4x4 Mixup (Edge-Split) features split edges that can separate when all are correctly aligned along the equator. It turns like a typical 4x4 Mixup puzzle, and can stay that way if you don't want to do the added setup/scramble feature. But doing so adds a new layer of complexity through this hidden edge mechanic. A mind-bending challenge for fans of deep-cut and shape-shifting puzzles.
