I won the fireworks magic pin twice but i only got one. Can you only get it once? Or is it like a bug?

Yes, I believe you can only get the Fireworks Magic Pin once per account.

Yeah it is only once, they want to make them harder for people to get. If you won them each time some people would have them coming out there ears by now.

Ok, thanks. So the only Way to get it is to trade? (or mule account)
