This is a set consisting of one large plate, two small plates (small bowls), and one condiment dish. These items have been stored in a cupboard since the Showa era, and their frequency of use and origin are unknown. There are no markings. The color is a glossy black with a partially rough-textured blue appearance, making it stylish. As these are old items, there are scratches and stains. Please check the photos. #SmallBowls #DeepPlates
