Try-Bal 332 is a tricky puzzle where the aim is to fit the 6 sphere based pieces into the tray.
You need to place all the pieces in flat so they create a 3 x 3 x 2 shape inside the base.
Four of the pieces are the same and the two others are unique. It seems like this would make the solution fairly easy to find but this is actually a challenging puzzle.
The tray is made from a really nice variation of woods that looks very attractive.
