This is a cup and saucer from Koransha's representative Orchid Lace series. Koransha items are made of thin Arita porcelain. It's a leading Japanese brand, and all of their products are expensive. This eggplant-navy cup might be discontinued, so it's probably hard to find. I love eggplant-navy and orchids, and I used to display them in a curio cabinet. Although it's unused, I've washed it once, and I've taken everything out of the box and displayed it for many years. If anyone likes it, please consider purchasing it. Reference price: ¥6160 per cup 5 cups: ¥30800
