Mino Ware Iga Covered Fugu Fin Sake Cups and Bamboo Covers Set of 4 each Diameter: Approximately 6.3cm, Height: 9cm, Capacity: Approximately 180cc Used once after purchase and then stored on a shelf. Perfect for the coming season. Please use them! Not just for fugu fin sake, but also for hot sake! Since there is no box, I will pack them carefully, but I cannot be held responsible for any shipping accidents. Magazines, etc. (recycled) may be used as cushioning material to fill gaps in the cardboard box. Thank you for your understanding. Thank you.
