4D Box Pro

Effect: You open a wooden box and show three elegant wooden balls inside. You take out the 3 balls and vanish them one by one, using any type of vanishing method you want (e.g. a change bag or sleight of hand). Once all three balls have vanished, you reopen the box to find that the three balls have reappeared inside.

4D Ball Box Pro by Conan Liu has a huge improvement over the original principle: There's no holder or any kind of visible interlayer attached to the lid or the box. The box including its lid can be examined by the spectator right after the performance.

The triggering method is revolutionary and clever. During the entire performance, when to trigger the gimmick to make the balls appear is all up to you. You can decide if you want the extra balls to appear or not by opening or closing the box in a different direction.

We have eliminated the redundant base plate that most other variations have (the base plate is so likely to deform as temperature or humidity changes), making our box more durable than others.
