Madge's mocking-jay pin
Although it can be hard to fathome, this little pin was a huge slap in the face for the Capitol. Presented loud and clear for the world to see is the mocking-jay placed in the center of the pin.
Solid gold all around, Madge's mocking-jay pin is a sign of rebellion among the Districts. Based off a experiment gone wrong in the labs of the Capitol, the pin is true to it's name and mocks the Capitol on it's mistake.
