Apart from the original Slinky, several other varieties exist. There is Slinky Jr., which is about half the size of the original. You can also find glow-in-the-dark Slinkies, as well as Slinkies made out of solid brass, and gold plated slinkies, called "The Executive Slinky." There was also a 50th Anniversary collector's edition Slinky put out in 1995. It is a darker colour metal than the regular Slinky, and comes in a replica of the original Slinky box.
