EUC Set of Vintage Japanese Blue Iris Tea/Sake Cups

In excellent vintage condition. No chips or cracks and the flowers look great. I don’t see any loss of color. The irises are a gorgeous shade of blue and periwinkle with bright and muted green leaves and gold accents. Back and interior of the cups are solid black. Please see pics for measurements. The cups stack fairly well, too, for storage. They are very reminiscent of the Otagiri Blue Iris set, but are unmarked and have slightly more detail. Bundle and save!!
