This is a product from Miyai Co., Ltd. in Kyoto. It is a favorite of Shoko Uemura and comes in a paulownia wood box. It retails for around 10,000 yen. I purchased it at a hobby shop. * There are fold marks and sun damage in that area. I haven't used it, but I discovered it upon opening it this time. It appears to have been sun-damaged at the store. See photo 3. * Inscribed with the name "Yoshida." * Size: 65 x 65 cm
