Frank Castle uses one of the Punisher Symbol Shiny Pewter Keychains to keep everything organized. He has keys for his guns, grenades, gun lockers, grenades lockers, gun and grenade lockers, lockers for the lockers, and the keys for the Home for Wayward Kittens. Gotta make sure those kittens are well taken care – he loves those kittens if you know anything about Marvel’s Punisher! The Punisher Symbol Shiny Pewter Keychain is a 3 inch symbol that we’ve all come to recognize from good ol Frank.
