These pips are exact reproductions of the ones worn on the 3rd-7th seasons of Star Trek: The Next Generation, as well as the first 5 years of Star Trek: Deep Space Nine. They are available in black and gold, but this listing is for gold. They measure 7/16" across and are mint, unworn pins. Made by the Hollywood Pins Company, they have had limited release and are not easily found outside of Star Trek conventions. Hollywood Pins closed down in October 2001 so these pins will soon be next to impossible to find.
