Trivial question re birthday badges

[Caiti19]

The birthday badges that come with a birthday card. Why don't they come with safety pins anymore? Health and Safety? Are the ones with the plastic prong on them that seem to be everywhere now supposed to be put over the neck of a jumper or what?

Thanks in advance for the enlightenment.

I’m nearly 40 and I remember they’d removed the safety pins when I was in my mid teens, it’s not a new thing
