Made by Tanaka Isseki, Ryukei Suzuri (Inkstone), Large Size Natural Inkstone with Lid This is a "Uchiwari" technique, where the stone is split in two, with the top used as a lid and the bottom as the inkstone. When the lid is closed, the cut surfaces fit perfectly together, forming a single stone. ⭐︎ It's a hefty, large size. Size: Length: 20cm (approx.) Width: 11.5cm (max) Height: 11.5cm (max) Weight: 3.7kg Bottom (Inkstone): 1.7kg Top: 2kg Inkstone made from "Ryukei Stone" from Nagano Prefecture. Ryukei Stone is a raw material of black mica slate, produced from the Tenryu River system, and has been quarried since the Edo period. Designated as a traditional craft of Nagano Prefecture. Mr. Tanaka Isseki's works are appreciated not only as "inkstones" but also as decorative items, like "three-dimensional sculptural objects" that make the most of the natural shape of the stone. They are also treated as antiques and collectibles, and are even subject to cultural property collection. Unused, long-term storage. I hope it will be appreciated by someone who will use it. Thank you.
