This is a vintage set of 3 small pins/brooches made by @JOY. They are a retro style of resin filled with gold-tone metal edging. I think they would date back to the 1960 - 1970's. These are small shoulder pins. They each measure about 1" x 1/2". The three pieces include one small purple resin butterfly, one small blue resin butterfly and one small pink resin flower.
These pieces are each in very good condition. The pins work well on all three. Each have the @JOY sign around the edge of the gold-tone metal.
