Direct from the manufacturer, quality assurance!!! Earthquakes, typhoons, tsunamis, tornadoes, floods, and other natural disasters are increasing in frequency. When natural disasters strike, they often come with water and electricity outages, food shortages, communication disruptions, and transportation disruptions. Rescue personnel cannot enter the affected areas to provide assistance, and before the rescue personnel and supplies arrive, we can only rely on our own efforts to carry out self-rescue and mutual rescue. This requires certain tools. Our self-rescue box, with its multi-functional features and convenient portability, is an essential outdoor item. Friendly Tip: The whistle, small pliers, and fire-starting rod inside are shipped at random in various colors.
