Long plate: 28 cm wide, 19 cm long Small plate: 14 cm wide, 10.5 cm long These items have been stored in a storehouse for a long time, so they are for those who don't mind minor imperfections. There is a marking on the back, but it cannot be deciphered. It looks like Kurumayama ware, but I couldn't find the corresponding kiln even after searching. They will not be placed in the current box.
