Take the star apart from his cage and put it back, that is the objective of this beautifully metal puzzle.
A word from the designer:
"This brass puzzle was first introduced to me by Prague's own Professor Bakalar. I borrowed it in Atlanta and returned it to him in Luxembourg half a year later. While in my possession, I managed to replicate it, with full permission, of course. This Cast Puzzle version may even be better than the original. It definitely remains one of the more amusing puzzles. The key idea with this one is its 'cage'."
