I purchased these previously on a certain auction site. They are pins from Toho, Toei, and Shochiku. I'm not quite sure what they are, but are they something to attach to the lapel of a suit? They might be for employees, but the details are unknown. One from Toho One from Toei Two from Shochiku A total of four. They are small, and I've taken a picture with a 10-yen coin for comparison, so I hope it helps.
