The AVC Box is a super practical prop. Use it to make things Appear, Vanish, or Change! This is fantastic for many different routines and is especially useful when working with silk. Put three large silks inside, then open the box and show they have vanished and in their place is one giant handkerchief. Or, show it empty and then produce a big load of silks.
We use this prop in our shows for mis-made flag routines, 20th Century Silks, and similar effects.
