The buttons above are the most unusual and I am hoping someone will read this and educate me. They feel like some sort of composite material and seem to be molded around a metal shank. You can see the backside of one in the center at the very bottom. Those N or Z shapes are sparkly and there are sparkles in the art deco fans. A lot of buttons have passed through my hands but none like these.
The Light of Spring!
