The Imperial is a plastic looping yo-yo with a fixed metal axle, starburst response, and a narrow string gap. Its profile is based on the older wooden Tournament 77 model.
Even though it is kids' stuff compared to more modern looping models such as the Yomega Raider, the YoYoFactory Loop 1080 and even Duncan's own Hornet, it had seen plenty of use back in the day by even the professionals, especially the legendary demonstrator Barney Akers.
- An opaque yellow Imperial was the first yo-yo sent into in space, on April 12th, 1985. This was a part of a series of scientific experiments called, "Toys in Space", where different toys were tested in outer space to see how they are affected by weightlessness. Originally, a Tom Kuhn No Jive 3-in-1 was going to be the first yo-yo in space, but because it was made of wood, it did not meet NASA's safety requirements.
