Self-defense keychains are small, portable tools designed to help individuals protect themselves in threatening situations. They often come in various forms, such as kubotans, pepper spray, or tactical flashlights, and can easily attach to a set of keys for convenient access. These keychains are intended to empower users by providing a means to deter or escape from potential attackers. Many self-defense keychains are made from durable materials, ensuring they can withstand impact. While they are not a substitute for professional self-defense training, they can serve as a useful addition to personal safety measures. Users should familiarize themselves with local laws regarding the use of self-defense tools.
