Oh, for goodness sake!
A beautifully crafted, titanium sake bottle that will hold approximately 540ml of liquor. If you're a weight savvy adventurer, you are sure to appreciate the use of titanium. It's well known that titanium is a lighter material than steel, and much stronger than aluminium - therefore weight & durability won't be an issue. The bottle has a single wall construction which makes it easy to cool if placed in cold water. It is important that you don't heat the bottle's body or cap directly with fire, or boil it. You must also be weary that there is a danger of deforming the bottle's main body when the drink is put in the freezer.
