The structure prevents heat from your hands from being transferred to the drink, so ice does not melt easily and hot drinks do not cool easily. Even if you put ice in it, it does not easily get condensation and does not change the taste of the drink. Titanium is a metal that does not rust, so the metal does not dissolve into the drink. This means there is no unpleasant taste or metallic smell, and you can enjoy the original flavor of the drink.
