This is a tea cup and saucer set from Kozan Kiln, featuring a deep blue hue delicately adorned with purple flowers. The transparent coloring and soft brushstrokes create a harmonious balance, exuding an air of refined elegance. There is hardly any sign of use, and both the cup and saucer are in excellent condition. The "Kozan Kiln" mark is present on the underside of both pieces, indicating careful craftsmanship. This is a high-quality item that will enrich your special moments. Thank you for your consideration.
