Description of the author:
Hollow Mystery is a hollow Jaap's Sphere version of Rocket Twist, illustrating its unique geometrical properties. The puzzle has three squares, four triangles and three "diangles" wrapped around a sphere. At its initial state, the puzzle has three rotation axes, each 10.8122 degrees north of the equator, and equally spaced around the north-south axis. The puzzle has three main cuts, which is the south pole revolved around each of the three rotation axes. Hence the three cuts intersect at 120 degrees at the south pole. One of the triangles is centered at the north pole. The other three triangles are surrounding the south pole, bound by the three main cuts and three stored cuts. Hollow Mystery has the unusual property that its rotation axes are not stationary, but they move around. When one side is rotated by 144 degrees over rotation axis no.1, then rotation axis no.2 remains, but rotation axis no.3 disappears. This is usual behaviour for a jumbling puzzle. However, when next a rotation of a side is made by 144 degrees over rotation axis no.2, then rotation axis no.3 reappears at a different location, at 72 degrees from its original location. With other combinations of rotations, also axes no.1 and no.2 moved around the sphere. The puzzle is definitely a jumbling puzzle, as it cannot be unbandaged into doctrinaire puzzle. The puzzle is also definitely quasi-doctrinaire, as any state of the Rocket Twist (or Hollow Mystery) is at most one turn away from a "rocket-shape" state. It is undetermined whether the puzzle is deeper-than-origin, as the moving-around of axes happens both when the puzzle is played shallowed-than-origin and deeper-than-origin.

I think it's better than you could expect from a printed puzzle. Perfect turning, perfect stickers, polished surfaces. Maybe a bit too big, but the shape makes it comfortable to play with.

The stickers have been cut and applied very nicely, and the puzzle looks and turns great.

My only complaint is that I scrambled it a couple of weeks ago and still have made zero progress in solving it.. I forgot I suck at bandaged puzzles :D
