Puzzle info.:
We   have been prepared for these cubes for more than half year. This is a   co-operated project between Mr. Bao (Mr. Dayan), Tom and HK Now Store.   These cubes consist of 3 main parts, the Dayan Bermuda Cube body, mf8   Crazy 3x3 center-core locking mechanism and Tom constrained center   parts. The center pieces are relatively large so as to highlight the   constrained features.
