This is a sake cup by Keito Sakaba, a ceramic artist from Mito. Size (approx.): Cup: 8.5cm diameter, 3.3cm height Box: 11cm length and width, 6.5cm height It's thin and light, with a slight blue tint overall. The three crabs are humorous and refreshing, making you want to enjoy some delicious sake. Although unused, there are stains on the box and cloth due to long-term storage. I think it's rare to find a Sakaba piece with its original box. Also, the "Kei" mark is rare. #Rakugakito-bo #Kutaniware #Colored-e sake cup #Guinomi (sake cup)
