In The Clear by Nicholas Lawrence

A stunningly visual and practical method for switching objects IN PLAIN SIGHT. Use it secretly as a switch OR BOLDLY AS A TRANSFORMATION.

This looks like special effects. Well, it does if you want it to. "In the Clear" is such a perfect switching device that you can do it secretly to switch an item without anyone realizing it, or you can direct everyone's attention to it and perform JAW DROPPING transformations inches away from their eyes.

THE BEST PART? Use ANY deck. As long as it comes in cellophane, it'll work perfectly.

The box is normal and examinable. No cuts or slits are made in the card box so you can really use any deck. The cellophane is also fully examinable.
