Description
mf8 Double Crazy CubeThe mf8 Double Crazy Cube isn't your standard crazy 3x3. Each face has a double ring on it. On the red orange faces, the inner circle remains stationary while turning. On the white yellow faces, both rings move with the face. And on the green blue faces, both rings remain stationary. This leads to very interesting solutions that are quite the challenge. Give it a shot if you think you've got what it takes!

Perfect fit
Perfect fit for the toothbrush. We have a different brand of toothbrush (also from Amazon) but it has been discontinued. But these replacements fit perfectly.
