This item's value is steadily increasing. It comes with a certificate. As shown in the photos, it will be included. This is a work by Jiro Kinjo, a Living National Treasure of Okinawa. I splurged and bought it in Okinawa several decades ago. I am selling it because my collection has grown too large. This is an item whose value will continue to rise. I will pass it on to someone who will cherish it. I have kept it in a bag since I purchased it, so there are no scratches or stains. It is relatively beautiful, but it is an antique, so please understand. Similar items were listed for around 70,000 yen. I am selling it at a lower price because it is a private sale. Price reduced.
