This is a set of four natural wooden coasters with a warm atmosphere created by the slightly different wood grains of each one. There are no noticeable scratches or stains. They are generally in beautiful condition. ● Diameter: Approximately 12cm ● Height: Approximately 2.5cm ● Material: Wood The type of wood is unknown, but it has a slightly reddish dark brown color, and the swirl in the center prevents the dishes from slipping while also serving as a cute visual accent. The diameter of the recessed center is about 5cm, making it a suitable size for guest teacups and small dishes for sweets. The slightly different wood grain patterns are beautiful, and these coasters have an elegant, Showa-retro feel. They don't take up much storage space and are a useful set of four for when guests arrive. If you are looking for high-quality coasters or if you like natural lacquerware, please consider these.
