These are mid century assorted flower drapery/curtain pins.  They are different measurements.  In the first photo top left to right - yellow flowers measure about 2 1/4" x about 1 1/2".  The center top is yellow with red accents in umbrella measures about 2" x 1 1/2", last on top row pink measures about 2 3/8" x 1 1/2".  The bottom row are the same style, different colors and they measure about 1 3/4" x 1 3/4".  The back pins are all about 3/8" long.  They are in guardedly good condition with some varied wear as shown in my photo's.
