Diameter: Approximately 23.5cm Thickness: Approximately 2cm This is a Yosegi-zaiku (parquetry) round tray with a beautiful combination of natural wood colors. It's not made with thin slices of wooden mosaic, but the pattern goes all the way through. This is called "muku" (solid wood), and it's a high-quality piece of Hakone Yosegi-zaiku. It's generally in good condition, but there are slight storage scratches that are only visible depending on how the light hits it. I think you can use it without any worries.
