Purchased approximately 2 years ago. Used in various situations such as mountain climbing, camping, and drinking coffee outdoors. Selling because I purchased a new cook set and its usage has decreased. Images 1-7: From the official website. Images 8-10: Show signs of use on the bottom and inside. Image 8 is everything included. No outer box. From the official website: Cookware combo with versatile combinations. A Thermostack (multi-functional mug set) with a 750ml large mug for cooking, a mug lid, and a cozy (insulation case) are included. Can be used in various combinations depending on the situation. ① For long-distance hiking, use all three mugs to prepare meals and hot drinks. ② For day hikes with meals, choose two mugs to carry. ③ Stacking the mug 350 and mug 400 provides heat and cold retention. ④ Each of the three mugs can be used individually. #soto #cookware #cookwarecombo
