EVERY PURCHASE COMES WITH FREE STRIKING TRAINING
Your purchase includes a striking training video so your daughter can learn to protect herself wherever she may be. While carrying a self-defense tool is essential, knowing how to use it effectively and having the ability to react quickly in dangerous scenarios is just as important.
