You display two boxes on a tray.
Each box has a round cutout in front with a sliding window and a hinged door on top.
When rested on a tray they appear to be like a die box. Show a Die and place it in one box and it magically travels to another box and vice versa.
Finally the boxes are SPLIT from the tray but still the die invisibly travels from one box to another.
The special feature of this model is that at any time you can show the die has appeared or disappeared from either of the box.
Finally open all the doors and windows of both boxes and show that the die has completely vanished and reappears from a hat or elsewhere.
The whole outfit measures 10 inches high, ten inches long and five inches deep.
