Fullmetal Alchemist Brotherhood - Edward Elric Pendant
Any self-respecting fan of the series should get their hands on this, whether it is part of the set or on its own. Not just for having it, but from a cosplay standpoint as well. This particular pendant (there are others) is of Flemel's Cross and it is the symbol familiar to all FMA viewers that we see in the series. It is on Edward Elric's jacket and his brother, Alphonses armour suit.
