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.
