Approximately 9 centimeters in diameter. This is a commemorative item. The bottom of the cup is engraved with "Ministry of Internal Affairs and Communications," "Award," and "silver f." If you would like the item with the box, it will be an additional 500 yen (shipping will be changed to Takkyubin). I will change the price, so please comment before purchasing. The date and name are written on the back of the wooden box.
