Puzzle Details
12 sided puzzle with 6 rhombic and 6 trapezoid faces. Means, this puzzle has a top and bottom in a way:
Three rhombic faces (like yellow - red - orange on the second image) build the top and the bottom cap. These caps are connected by the trapezoid faces, as seen on the 'side view' picture.
Although it looks like, not all peaks can be twisted. the triangles on top and bottom are blocked by an inner cubic structure.
The puzzle has been stickered and adjusted perfectly by Eric, it is really a gem.
