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 personal alarms, and can easily attach to a set of keys for convenient access. These keychains are intended to provide a sense of security and can be used to deter potential attackers. Many self-defense keychains are made from durable materials, ensuring they can withstand impact if needed. 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 self-defense tools to ensure compliance.
