This is a "Satsuma Kiriko" ochoko (small sake cup) by Kuniaki Kuroki, a "Contemporary Master Craftsman" recognized by the Japanese government for his outstanding skills. According to the official website, he participated in the Satsuma Kiriko restoration project in 1985, so this item is believed to be approximately 40 years old. Of course, it is an extremely rare item that is no longer produced. The artist was selected as a "Contemporary Master Craftsman," the first in the field of glass art to be recognized by the government in 1991. He is said to be the person closest to being a National Treasure in glass art. This is a top-quality Satsuma Kiriko, featuring vibrant colored glass with delicate and bold cuts. With a substantial weight, the overwhelming beauty of the cuts, and a presence that surpasses the photos, I believe this is a wonderful item. It maintains the lustrous and beautiful condition it had when it was made. We generally do not plan to lower the price in the future. This is a very wonderful item, so please consider it. Size: Diameter approx. 65mm, Height approx. 50mm Accessories: Original box, 2 pamphlets Although it is an unused, beautiful item, it is different from new as it has been stored at home for a long time. There may be minor scratches, stains, and age-related deterioration that I may not have noticed during storage. Please refrain from purchasing if you are looking for a new item like those purchased in stores or if you do not understand used items. Please note that we may use recycled packaging materials. Due to the nature of the product, returns and refunds are not possible. Please consider purchasing with your understanding.
