From the Marvel Stack-ems plastic keychain line, we have the Iron Man Stack-ems Plastic Keychain.  Measuring 2.5" high, this chubby little, bullet shaped keychain is ready to be attached, or "stacked", to other Marvel Stack-em keychains to form......MEGA MARVEL STACK-EMS SUPER KEYCHAIN XOO6! Ok, maybe not.  Anyway, this Iron Man Stack-ems keychain is here to help you organize the keys to your older Iron Man Armors; y'know, the ones that still need a key to turn the dang things on!
