You are faced initially with a totally enclosed box which you must determine how to open. Its not so easy..... When this is solved and you disassemble the puzzle you will find there are 6 pcs. There are notched sticks attached to each of the 6 sides of the box. They will interlock when assembled properly to reform the box. For you burr puzzle fans, this is essentially a 2x2x2 burr puzzle with the added complexity of the sides being attached. Very cool puzzle....
