Very Jolly 1970s Enamel Butterfly Brooches. I actually had one of these when I was a kid...a most prized possession. The bigger ones are 4cm wide, the smaller ones are 3 - 3.5cm and theya re made of a light metal with a secure catch on the back.
The two at the bottom left on the main photo are glittery and sparkly. I've also just found a blue one. Some come on original ALL THAT JAZZ cards.
If you'd like one on a card please let me know. They came from the packed up stock of an old seaside jewellery shop that closed in the 1980s.
