HORIE has felt an affinity with titanium, a unique metal that caught their eye whilst looking for a suitable metal amidst many others for their metal treatment technology. The Horie metal treatment alters the surface colours of titanium to give off a unique gradient hue. They believe that good optimisation of the products' characteristics can bring out the true value of metal products. The Double Wall Titanium Tumbler is designed for better insulation - both hot and cold. With its double-walled feature, ice can be kept much longer without much surface condensation, whilst hot drinks can be kept warm longer, without burning your hand. Such is the consideration given to the simple act of drinking from a glass.
