This is a beautifully colored sake cup. There is a mark on the bottom, but I don't know what it is, but it is an item that has been very carefully stored. There are some stains and color fading, but for an item of this age, it has been relatively well-preserved for guests and I don't think it's particularly noticeable. The flowers, such as chrysanthemums and bellflowers, are painted in rich colors and are beautiful. Please check the photos. This is a very old item, over 60 years old. Diameter: Approximately 5 cm Height: Approximately 6 cm The colors are similar to Iro-Nabeshima ware, and it uses colors like yellow and purple, which I think is rare. It's very cute! I will sell it to someone who likes it. Antique Vintage Antique Guinomi (sake cup) High-class restaurant
