This Tamahashi tumbler is built with a double wall stainless steel structure and finished with an antique silver plating that oxidizes into a distinctive blue green patina for a one of a kind look.
The cup is made of 18-8 stainless steel and hand polished by skilled craftsmen to bring out fine detail in the finish. It is produced in Tsubame, Niigata, Japan, a region known for its metalworking, and carries the official Made in Tsubame mark.
