I have a set of 4 vintage drapery pins.  They are plastic.  1 of the center flowers have come unglued.  They measure about 2" across x about 5/8" in depth with the pin extending another 3/8".  2 of the flowers center pedals are broken, not that noticeable - I almost missed it.  They are in nice condition otherwise.
