This is a dedicated item. A set of ceramic tokkuri (sake bottle) and sakazuki (sake cups). For warm sake in winter, and chilled sake in summer. It appears to be for 2 go (a unit of volume, roughly equivalent to 360ml). I bought it intending to use it, but I never did, so it's a waste. I'm offering it to someone who needs it. I don't know the type of pottery or the brand. I think I bought it for just under 5000 yen. It's new and unused, but it's still a used item from a household. The original cardboard box is also damaged. I hope you understand. If anyone is interested. The items in my home have not been purchased as recycled goods. They are from department stores and select shops in the city. - Material: Ceramic - Color: Black - Set Contents: Tokkuri, Sakazuki, Sake set - Shape: Rounded design Thank you for looking.
