This is a rotational puzzle that comes from Meffert's Puzzles.  If you like the Rubik's cube then you will love this 6 color rotational puzzle! To open the treasure chest the puzzle must be solved.  There is enough space on the inside of this puzzle to add a 'treasure' of your own and give it as a gift.
The secret compartment inside is 4.5cm / 1.75in
Designer: Oskar van Deventer
