The Brutus Bulldog Self Defense Keychain offers a method to defend yourself from attackers disguised in the form of a keychain.
This self defense keychain is made from acrylonitrile butadiene styrene (ABS), a form of plastic that is unbreakable and as strong as metal. The ears of the Brutus Bulldog Keychain not only extends your reach but are also able to pierce softer substances. The eye holes are about a 13 ring size and should fit most people, though you might want to check what your ring size is before you get one. In addition you should also check what the law where you live says regarding possessing a concealed weapon of this variety.
This self defence keychain is available in a rainbow of colors that are sure to impress your assailant right before you knock him out.
