This is a set of a USB rechargeable LED headlamp and a survival whistle. The headlamp has an elastic strap and is removable, pocket-sized, and can be used on its own. When it gets a little dark, charge it with a Type-C cable. It has 3-stage angle adjustment and a magnet, so it should be useful on car bodies and in various situations. The orange part is the switch, and you can open the cover to charge it. It's 8cm long, 2.5cm wide, and weighs 44g, making it ultra-lightweight. It's very bright, allows you to use both hands, and has two light patterns, making it ideal for outdoor activities, night fishing, and nighttime work. The survival whistle is made of ABS material and is army green. It's a thin type, 7cm x 2.8cm x 7mm x 8g, and comes with a chain. The description mentions a dolphin sound. Use it as an essential item in case of disasters, along with the light.
