Noritake melamine ware, a set of two, blue and yellow. I don't know the exact age, but I think it's from the 1960s to 1980s. I'm not sure what they're for, but I think they're plates. The size is about 21cm in length and width, and 1.5cm in height. The condition is good on the front, but there are scratches on the back (please check the 6th photo). Thank you!
