These titanium rock cups are handcrafted and polished with care by artisans in Tsubame City, Niigata Prefecture. The body of the cup has a calm appearance with a blasted finish. Titanium is lightweight and doesn't rust, making it a very easy-to-handle cup. The double-walled construction makes it less prone to condensation and maintains the ideal temperature for your drink, keeping it hot or cold. It comes in a wooden box, making it perfect for gifts. ■Product Specifications ○Item No.: TW-4 ○Product Name: Kasumi (Mist) Titanium Double Rock Cup Set of 2 (Wooden Box Included) ○Main Material: Titanium ○Finish: Blasted ○Capacity: 250ml ○Size: Diameter 78 x H85mm ○Weight: 90g ○Country of Origin: Japan Thank you.
