This little "classic" utility prop never fails to mystify. A polished 3" x 2" x 2" chrome box is shown inside and out by opening the sides and top. The audience can clearly see that the box is empty, but after the doors are closed and the magic words are said, the top is opened and silks, ribbons, sponge production items, etc. are produced. You can even take the box apart, put it back together and then produce items from within!
