Thank you for viewing. This item is made by hollowing out the thin part of Kitayama cedar, produced in Kitayama, Kyoto, and comes with a copper drop-in (see photo 4). The smooth, glossy surface has knots and dents, and the annual rings can be seen from the top and sides, showcasing the beauty of Kitayama cedar in a small package. The body has a brand of Kitayama cedar (photos 2 and 4). There are no markings indicating the manufacturer, but I believe it was given to me along with a flower basket that I purchased at a shop. It has been unused and stored for a long time since I received it. 【Size】 Height: 28.5cm Thickness: 4.7cm (at the thickest part) Thank you for your consideration.
