After purchasing Playmaxx, Duncan ran a number of test runs with their newly acquired molds. The Dragonfly was Duncan's release of their version of the popular Playmaxx Bee GT. In this case, GE (General Electric) made a run using their patented Enyo plastic. I understand that the run was paid for in Enyo yo-yo halves, given in payment to Duncan, which became Duncan's Limited Edition Enyo Dragonfly.
Enyo plastic (Lexan Polycarbonate resin) creates the appearance of tiny crystals in the plastic creating all sorts of color effects inside the yo-yo. And it is a very tough plastic as well.
Several side caps were made for the GE run. Click on the Reverse view to see one of the alternate sides on the reverse.
