Thank you for viewing. This is an antique item that came out during the sorting of antiques. Please understand that I do not know the details. It says "Kenzan-utsushi," suggesting it is a work in the style of Ogata Kenzan (1663-1743), and it also says "Higashiyama," which I imagine is the name of the kiln. This is just my personal opinion. There are four flower-patterned sake cups and one different one, but the circumstances are unknown. I imagine the different one was added in place of a missing flower-patterned one. None of them are damaged and show no signs of use. The flower-patterned sake cups have the same design and are marked with the Higashiyama mark. Also, the different sake cup has a trick where the pattern appears when held up to the light, giving it a stylish atmosphere. ▪️Size (Slightly different from visual inspection) Flower-patterned sake cup: Diameter 5.5cm, Height 3.3cm Purple sake cup (different): Diameter 4.8cm, Height 3.7cm Wooden box: 16.5cm x 16.5cm x 6cm The wooden box is partitioned to hold five cups. There is some staining due to aging. Please judge the sake cups and wooden box from the photos. Please understand that this is an antique item from a non-smoking, home-kept environment. Also, please refrain from purchasing if you are sensitive to such things or seek perfection.
