Difficulty: Moderately Easy
Step1
Learn the law. Some states have restrictions on buying mace through the Internet and having it shipped to your home. In certain states mace must be registered with the police department. Contact your local law enforcement agency and ask about any restrictions buying and carrying mace.
Step2
Show proof of age. Most states require a person buying mace be at least eighteen years old.
Step3
Determine where you will be carrying the mace. It can be purchased in various size canisters. Select a size that will be portable. For example if you will be carrying mace while jogging a small canister on a key chain may be appropriate.
Step4
Select concentration. Mace which contains pepper spray usually comes in 10 or 15 percent concentration of the chemical irritate. Either strength will work as a deterrent against an attacker. The higher concentration may cause more irritation but costs a bit more.
Step5
Consider buying a large canister of mace for use at home. When selecting a home canister of mace portability is not an issue. A larger canister has a more powerful spray and may inflict more damage on an intruder.
Step6
Look for an easy to use spray feature. In a situation where you are fighting off an attacker you are likely to feel panic. You don't want to be struggling with twisting off a cap or finding the spray button.
