Is it just a box to keep your Zombie in? Of course it is. Also it is a beautifully made wooden box that allows you to start the Zombie effect while it is hidden in the box. The Zombie ball can either be placed into the box in front of the audience or started from the box. It mysteriously opens and the Zombie ball floats out. Comes in two sizes. Inside measurements are either 4 1/4 square or 5 1/2 square.
