I think that ring is listed a few times because they are different items..? Like one of them doesn't include the glass while the others do. I found similar props that are basically the same thing also
STAR TREK (2009) and STAR TREK INTO DARKNESS (2013) - Starfleet Pin Set - Current price: $50...
I've heard mixed reviews but I may have to give it a go especially since they got renewed. They definitely marketed it as a comedy but now that I hear it has some dramatic sci-fi moments its been officially added to my list. :geek:
