Secondhand, but in fine condition as you see at the photos.
You invite a spectator up on stage and place a black box over her head. Then you insert 5–6 dangerous balloon swords through the holes into the box.
When the door is opened, the swords can clearly be seen crisscrossing inside the box — and the spectator’s head has vanished! But with a little magic, you can make it come back again.
The box measures 36 x 36 x H 28 cm. There is a door on both the front and the back of the box.
