Pepper Spray contains a formula of 10% Oleoresin Capsicum with 2 million Scoville Heat Units (SHUs) that will immediately stop an attacker in his tracks. Additionally, the police will have no problem identifying who you sprayed because there is a vegetable dye contained in the pepper spray which easily identifies the attacker. This self defense pepper spray product is exactly what you need in order to help protect yourself in the event of an attack upon your person. It's an inexpensive method of immediately stopping an attack and allowing yourself time to get away and call the police. This PS-1 pepper spray in a leatherette holster made by Pepper Shot is small enough to carry on your keyring. Keeping your defensive spray accessible at all times is necessary if you plan on using it for self defense. If you have to fumble through a purse, pocket, coat or whatever in order to find it, you've already lost valuable (possibly life saving) time. You need to be prepared to use your pepper spray immediately if you are threatened. Keeping it readily available will ensure you are prepared both physically handling it and mentally prepared to employ it when necessary. By keeping your pepper spray on your keyring, you will mentally always be aware of it and it's defensive use; and you will have quick access it to it when you are threatened with violence. Pepper Sprays can not be shipped to New York, Massachusetts, or Wisconsin.
