Anthony's comments: "This is like the 'rumoured' two layer cheese by Rubik. The Rubik's Cheese is the three axis, single layer, of which there are a few around. I have one. I have seen what looks like a photo of the two layer but that is all. Whether it was manufactured or just prototyped seems to be a bit of a mystery. I have tried to find out but didn't get very far."

In 2010 this puzzle went into mass production in HongKong.
