Nuku-be Hiya-be (Warm-be Cool-be) This is a set of a tokkuri (sake bottle) and ochoko (sake cups) that can be used for both hot and cold sake. By putting hot water or ice water in the outer container, you can warm or cool the sake vessels inside. Because it uses a bain-marie method, it keeps the taste of the sake mellow, prevents the temperature from dropping easily, and prevents "kan-kuzure" (the deterioration of hot sake). Not oven, microwave, or direct flame safe. Approximate Size: * Main body: Diameter 6.2cm, Diameter 10.5cm, Height 16.5cm * Tokkuri: Diameter 2.3cm, Diameter 5.8cm, Height 17.5cm * Ochoko: Diameter 6.5cm, Height 4.2cm *Capacity unknown *Diameter is measured on the inside of the mouth, except for the ochoko. To check for cracks and breaks, the rubber surrounding the top of the tokkuri (photo ④ shows it attached) was removed, and there are places where the deteriorated rubber has stretched out and will not return to its original shape. Also, there are some rubber marks on the tokkuri body. The rubber will be attached as cushioning material and sent as is. Please remove the rubber when using. Although it is new and unused, the box has scratches, tears, and stains. For those who understand that this is a long-term home storage item.
