【Titanium Sake Cup Gold/Silver Unused】 This is a titanium W mini cup, a sake cup (without a logo), holding approximately 30ml. I received it at a New Year's drinking party, so I don't know the details, but I think the capacity is slightly smaller than a boundless sake cup. The outer diameter is 60mm and the height is about 30mm. Please consider purchasing, understanding that it is a used item. Neko FM
