I collected these when I was a child. They are Fujiya's Peko-chan, and Morning Musume's Maki Goto, Mari Yaguchi, and Hitomi Yoshizawa. Some of the pinbacks have rust on the back. You can't get them anymore. Thank you. Heisei Retro, Heisei Girls, Collection, Japan, Collection Group Name: Morning Musume 24 Item Type: Pinback Button
