Snow Peak's stackable titanium mug, the Yukihira M400 size. I haven't used it much and have been storing it at home, but I'm selling it. As you can see in the photos, it has a good appearance and I think it's in good condition, but it is a used item, so please only bid if you understand this. Uses/Purpose: Camping, Picnics Material: Titanium Type: Double-wall mug/cup
