Totally forgot I had these! A friend found them at a car boot sale a few years ago.
The set was released in 2005 when Star Wars Episode III: Revenge of the Sith came out. There are 7 badges all together, and each badge depicts a different character from the saga.
The pins are:-- Darth Vader
- Yoda
- Darth Maul
- Boba Fett
- General Greivous
- Clone Trooper
- Stormtrooper
