You are supplied with the shackle, chains and padlocks. Everything is normal and the padlocks are real. Take the two chains to either ends on the shackle and have your wrists locked into place with the padlocks. Once into position all you have to do is quickly turn around and make sure no one sees you push your wrists towards each other. The chains will slide and the gap of the chains around your wrists will become bigger and you can easily get out.
