Over 15 years ago, I had the opportunity to go on a business trip to China. During a day off in Beijing, I visited the Palace Museum and found the "Four Treasures of the Study" being sold as souvenirs for Japanese people in the museum shop. The actual items are said to be on display at the Palace Museum, but the museum has so many exhibits that I may have seen them, but I don't remember. I was also celebrating my 60th birthday at the time, and I thought it would be interesting to write postcards and letters with a brush, and I also thought they were interesting as crafts, so I bought them as a souvenir from China. However, I only wrote with a fountain pen at most, so writing with a brush was too difficult for me, and I never used them, leaving them in my desk drawer. I am offering them for sale, hoping that someone who writes small characters with a brush or is interested in antiques will be able to make good use of them. Please refer to the description written in Japanese. These products are said to be imitations of the items actually used by the Qianlong Emperor, the fourth emperor of the Qing Dynasty. The attached description is probably not a description of the actual items in the Palace Museum, but rather a description of these items themselves. * The material of the inkstone is fish roe stone. I have never seen a real fish roe stone inkstone, but if it is genuine, I think it is valuable. * The material of the seal is written as "Aoten stone," but I think it is a mistake and should be "Qingtian stone." * The ink is shaped exactly like the emperor's. * The brush is made of wolf hair. * The blue dragon depicted on the vermilion ink container is the emblem of the fourth emperor, and it is a celadon made 200 years ago. The vermilion ink is also made using traditional Chinese techniques. * All of these products are written as being handmade. * The pottery of the ink and vermilion ink container has the mark of the Qianlong era, but since they were sold as souvenirs and are imitations, I don't think they are from the Qianlong era. In China at that time, this kind of thing was common even in decent souvenir shops. I think these are miniatures made to imitate the real items for souvenirs. Please refer to the ruler in the photos for the size.
