This is not a mass-produced cube.
It's a custom cube.
It means that we can't buy this cube anywhere because it was created somebody in limited quantities.
I got mine from Vietnam.
Solving is easy only if you know how to solve the 3x3x3 cube.
Below are my photos showing step by step on I solve it.

If anybody is interested in getting this cube (not that cheap), please let me know.
