These are white plates and small plates from Richfield, a Western tableware brand of Tachikichi. They have a wave design. Medium plates: Approximately 20cm in diameter x 3.5cm in height Small plates: Approximately 15cm in diameter x 2.8cm in height There are 5 medium plates and 5 small plates. No box. These items have been stored at my parents' house for a long time and are from a collection of tableware being cleared out. They were stored stacked, so some plates have black marks (about 2mm) on the inside, and some have black marks on the outside. There is dirt on the edge of the foot (the part that touches the table). Please check the photos. Color: White Type: Plates Material: Ceramic Shape: Round Shipped via Rakuraku Mercari or Yu-Yu Mercari.
