This item was found at my parents' house. My mother said she received it from her grandmother but never used it, and she doesn't know how many years ago she got it or what it's used for. Similarly, I am not familiar with this product, so I may not be able to answer your questions correctly. There were no maker's marks or brand stamps on the box or the plates. Due to the effects of aging, the condition is considered almost unused. The gold coloring is beautiful, and you can feel the texture of the pattern when you touch it. It's a luxurious and lovely plate.
