This is a pair of pure copper cups for chilled sake from the stylish Japanese item brand Nakagawa Masashichi Shoten. New, they cost over 7500 yen. You can drink Japanese sake very deliciously with these. These pure copper sake tumblers will elevate famous sakes from ice-cold temperatures up to around 15 degrees Celsius. The tin lining on the inside also enhances the taste of Japanese sake, and the coolness of the copper provides a crisp feel, making them recommended for the upcoming season. The condition is used, with some signs of wear and cloudiness on the inner tin coating, but as you can see in the photos, they are in relatively clean used condition. The original paulownia wood box is also included. Please consider them! Thank you!!
