This is my Peter Venkman Ghostbusters costume and proton pack. Everything took me about a year to construct and source the parts.I have approx. $3,000 tied up in the entire costume. Everything is screen accurate, meaning its made from materials, and in some cases, the exact parts the Ghostbusters prop department used during the filming of the movie. The pack has lights and sounds and is VERY heavy. Lots of realism. This thing will do everything short of actually catching a ghost and holding it indefinitely. Thanks for checking it out!
