Here is a metal pin button that's fairly large. It's likely over or about 2 inches across & made of a thin sheet of metal curved at the edge so it's not sharp. It looks like it's been stained red/black with metal-compatible ink to create the design. It's designed like a soccer football with red & black pentagon pattern. In the central black pannel is the "Just the eyes & nose" Sonic design that was really popular for a while on merchandise in Japan. Here, the pin is still new in its package. This could have been a give-away or a UFO type prize because the package is plain/not really for display looking.
