Check out the Blackest Night 4 Infrared Spectrum Button Set, based on the emotional spectrum of Green Lantern lore! The infrared spectrum, however, is not the happiest of emotions to channel. Fear, Greed, Rage, and Death! So it is kind of like being invited to a wedding! Kidding aside the Blackest Night 4 Infrared Spectrum Button Set has four 1.25 inch diameter buttons, each showing off the symbol of their respective corps! Nekron, Larfleeze, Atrocitus, or Sinestro. Pick your leader and get cracking!
