This devious device allows you to produce a large quantity of silks from a seemingly empty tube. The magician shows a handsome metal, square, decorated tube. The tube splits in half, allowing spectators a clear view through both ends (see the picture). The magician straightens out the tube and proceeds to produce a large quantity of silks from BOTH ends of the tube. Each tube is sturdily made of metal, individually boxed and comes complete with instructions. Easy to do.
