This is the original Ultra-Star by Discraft. Used in the majority of competitive ultimate frisbee compeitive games in the world. This original stock print was very limited during the few years that Discraft issued the ring-less Ultra-Star. Rings (primarily for grip) were a patent of Wham-O manufacturing and were not added to the Ultra-Star mold until 1983 when the patent expired. Not many custom imprints on these Ulta-Stars were done.
