If you have road-rage issues you may want to steer clear of the 1.25'' by 2.25'' Hulk Age of Ultron Symbol Keychain. Or perhaps you wanna get the Hulk Age of Ultron Symbol Keychain! It all depends on how you feel about channeling your anger. If you are constructive with it like the Hulk in Avengers 2 then you should be good. Even if not, perhaps this lucite keychain will remind you what happens if you let somebody get into your head. I'm looking at you Scarlet Witch!
