Stun devices are specifically designed to get an attacker out of your personal space by administering a series of quick, painful shocks to the body through the skin. This 180,000-volt cell phone stun gun with personal alarm incorporates its unique design to give you a tactical advantage. No one will think that your "cell phone" is actually a non-lethal self-defense weapon. Choose from either blue or silver. It also has a safety switch to prevent accidental discharge. Cleverly designed right into a regular cell phone body so it's authentic looking, but it does not function as a cell phone. Free genuine leather carrying case included. Operates on one 9 volt battery, not included.
