A Star Wars movie wouldn?t be the same without droids. Some beep, some can speak over six million languages, and they all play important parts in the films. R2-D2 and BB-8 are the companions to the heroes in the trilogies and C-3PO provides funny banter with R2-D2 so fans understand more about the famed droids. All three of them come together in one stud earring set.
