This is a set of two hammered pure copper cold sake cups. I purchased them new and used them a couple of times, but haven't used them in a long time, so I'm selling them to declutter. There are no scratches or marks overall, but one of the cups has a mark near the bottom, so please check the photos. This is a series called Shokurakukobo, made in Tsubame City, Niigata Prefecture. The gold-plated interior type is still available, but the tin-plated version seems to be discontinued. From the official website: ■ Set includes: Cold sake cups x 2 each ■ Size: Cold sake cup / Diameter 52 x Height 54mm, 65ml ■ Weight: Cold sake cup (approx.) 41g ■ Material: Cold sake cup: Body / Copper, mirror finish, Inner surface / Tin plating Please refrain from purchasing if you are sensitive to used items. Thank you for looking.
