Come on down to South Park! They are all 1.5" in size not including the keyring.
Note: I understand that Craig's Gang includes Clyde and Token. They will come eventually~
BONUS: If you order all three South Park keychains in a combo, you get one of each as a button for free (sparkle or normal versions depending on which set you order). A $6 value, free~
Not officially licensed merchandise, but some really cool fan art!
