This is a puzzle of my own invention and consists of three ordinary playing cards that have been cut in a certain way allowing them to be interlocked along three axes. Your puzzle will come with an acrylic stand to display the burr once you have figured out how to put the three cards together. There are actually two ways to put the three cards together, but, only one way will allow the cards to fit into the stand properly.
The cards can be bent, but not torn or creased so that the finished assembly shows no cuts and looks quite impossible. The puzzle cannot be taken apart without tearing the cards, so it is a one time puzzle.
