This pin pack needs more information.
This is a simple carded package of 3 of the same gold-tone round metal pin. It has a star-ring edge & Sonic's face on the front. The confusing part is why the package is labeled "Segasonic & NiGHTS" NiGHTS came out quite "late" in terms of when the 'segasonic' branding was dropped. Then, what do the pins actually have to do with NiGHTS? Aside from the packaging, there seems to be no relation? And why 3 of the same pin? The back looks like it has info, but it's all in Japanese.
