2. Incredible Value

As you look across the various brands and manufacturers of self-defense keychains, you’ll see three categories to consider: basic, advanced, and luxury. Each is suitable for different situations.

  • Basic keychains deliver the essential tools to defend yourself, ranging from panic alarms to a Kubotan.
