SevenSeven's Titanium Tumbler is two layers of pure titanium. It keeps cold drinks cold and hot drinks hot, has no metallic taste, and is 60% lighter than stainless steel! It's a titanium tumbler for those who expect the absolute best, precision-designed by SevenSeven, thermally-insulated container specialists. Makes a great gift for that special someone! Pure titanium: imagining the possibilities ■ Titanium is light, strong, and rust-resistant; after years of constant use, it still looks like new! SevenSeven has long experience using industry-leading techniques in the careful crafting of items made from titanium and titanium alloy: we know how to bring out all the possibilities inherent in this cutting-edge material. ■ We're proud to announce the creation of a new tumbler from pure titanium, for a new drinking experience! The secret is in the two layers of pure titanium, with an insulating vacuum layer between them: don't be fooled by imitations. The insulating properties of the double-layer structure of this pure titanium tumbler are second to none: it keeps cold drinks cold and hot drinks hot! With our long experience and know-how in making thermally-insulated containers, SevenSeven is proud to finally offer a titanium tumbler unequaled anywhere else! c Copyright 2007 SevenSeven Co.,Ltd.
