At 1.75 inches wide and 2.25 inches high, the Green Lantern Symbol Acrylic Keychain shows off something we've never seen here...a Green Lantern symbol on something! You would think that we would have all kinds of things proudly emblazoned with the symbol of the intergalactic police force. There is what...3600 Green Lanterns in the universe? We would have surely ran into them at some point. At least we found this Green Lantern Symbol Acrylic Keychain, which shows off the famous symbol on both sides! I'm not entirely sure though if cars can run off solid will power...you should probably check. That's about as a green as you can get!
