Resin cast generic sci-fi rondelles. I custom designed these for a costume of my own but they can serve for any number of sci-fi/armored costumes and props. Rondelles are available in 4 sizes - 3.5 inches, 3 inches, 2.5 inches, and 2 inches. They are also available in both cold cast or plain resin. Cold casting is a process where metal and plastic (resin) are combined. The cold cast kit does have metal (aluminum) content in it, but it is mostly plastic. But it can be buffed and polish to have a real metal shine (see comparison photo). The three larger sizes also have cutouts that can be used for lighting the parts (see example). Questions?
