This is a new version of the classic coin penetration tube, but it was designed to give magicians a coin tube with three important important differences: it is brass, smaller in size and one or two coins can penetrate through the tube at the same time. Penny Tube is approximately 2 inches tall, precision machined in brass with an attractive design. It can easily be carried in your pocket. The tube screws apart at the center, so a quarter can be inserted. When the halves are screwed back together, the quarter completely blocks the center so nothing can pass through the tube. Unlike other coin penetration tubes, the performer can make one or two coins penetrate through the tube at the same time! Magicians will love the secret optical illusion used to tell the sides apart!
