This is the Evernew Ti U.L. Pot set 900+1300 ECA536. I purchased it new and have stored it at home, but I'm selling it because I haven't had a chance to use it. I washed it at home after purchase. The material is titanium, making it very lightweight. A dedicated stuff sack is also included. The stuff sack has a slight stain on the top. 【0.3mm Thinness Manufacturing Technology】 While standard titanium cookers use 0.4mm thin sheets, this Ultra Light series uses 0.3mm ultra-thin sheets, achieving a 20% weight reduction. It's not just about lightness; it's also about reliable manufacturing MADE IN JAPAN. Ti U.L.
