Purchased new from an outdoor shop three years ago and stored at home without ever being used. Retail price: 69,800 yen. The cardboard box it's in has slightly deteriorated, but I'll sell it to someone who doesn't mind. I will offer a small discount to those who purchase it, so please consider it. Quoted from the official website: The LifeSaver Jerrycan is the world's first portable ultrafiltration UF water purifier capable of removing all currently identified microorganisms, including viruses, bacteria, and cysts, and has saved many lives through humanitarian aid and other efforts for over 10 years. LifeSaver products are designed to withstand considerable impact, anticipating disasters such as earthquakes and typhoons. In areas with frequent natural disasters such as earthquakes and typhoons, it is an essential product for disaster preparedness because it allows you to secure clean water in various places even in emergencies. Also, because it can generate clean water from any freshwater source such as lakes, streams, and rivers, it is ideal for outdoor activities such as camping and backcountry exploration, as well as for long-term stays abroad.
