Measuring 1.25 inches in diameter, the Thor Hammer Icon Symbol Button is an officially licensed button from Marvel Comics and Odin! I'm surprised they even got him to come to the table as it were here on Midgard. That guy really doesn't like coming down here but hey, he wants you to don this great button! 

Based on Marvel's Mighty God of Thunder, this Thor button proudly displays the symbol of his chosen weapon, Mjolnir. It's a magic hammer capable of flight and totally smashing things up! Whatever you prefer, you know?
