Bruce Banner tends to lose a lot of keychains...and shirts and pants now that I think about it. Probably why I can't find any purple pants these days. Anyways, the Hulk Seatbelt Keychain w/Snap-On Belt Loop gives the ol' tip of the hat to Marvel's gamma rage monster person thingy the Incredible Hulk! The Hulk Seatbelt Keychain w/Snap-On Belt Loop is 4 inches tall and features a double ring configuration so you can load up all of your keys to your gamma ray chamber or hadron collider AND this keychain has a classic headshot of Mr. Smashy Smash himself!
