Two plates. I believe they are made of copper or brass. They are old items. Size: Diameter 10 cm, Height 2.5 cm There is a marking, but the maker is unknown. I purchased these long ago at an antique market and used them to hold small items. These plates have a nice patina depending on their use, so they are recommended for those who like iron. How about using them for accessories, incense holders, or ornaments?
