This is a set of two copper tumblers, each polished with care by craftsmen in Tsubame City, Niigata Prefecture, Japan. The bodies feature a hammered pattern, giving them a Japanese modern design that blends Western tableware with a Japanese aesthetic. The inner surfaces of the cups are polished by hand by craftsmen to create fine, frothy beer when poured. Presented in a wooden box, these tumblers have a luxurious feel and are perfect for gifts. Pouring cold beer into them will chill the vessels, keeping your drink refreshingly cold. ■ Product Specifications ○ Item No.: CNE976 ○ Product Name: Shokuraku Kobo Tumbler 450ml 2PC Set (Wooden Box, White Sleeve Included) ○ Contents: 450ml Tumblers x 2 ○ Main Material: Copper (Body) ○ Capacity: 450ml ○ Size: Diameter 82 x H132mm ○ Weight: 152g x 2 ○ Country of Origin: Japan Thank you.
