Approximately 29.5cm in diameter. This item is unused, but has been stored at home, so please understand. The box has considerable damage. I have several other items for sale. Discounts are available for multiple purchases. Please take a look if you'd like. Especially for bulky items like tableware, I offer a discount of 1000 yen for combined shipping, 2000 yen for three items, and so on. Please consider this.
