I'm not very familiar with it, but I believe it says Nishidou Kiln. Diameter: 16-16.3cm Height: 3.8cm Please allow for some error as these measurements are approximate. These were used for events like Buddhist memorial services, so they weren't used very often and are in good condition. However, they are used items, so please understand this before purchasing. There is no box, so they will be shipped in a cardboard box. This is a set of 5, but I have 10 in total. Please feel free to inquire if you would like to purchase more.
