I purchased these in the United States. I have two of them, but there's a size difference of a few millimeters (see the last photo, which shows them stacked). They're milky white plates, similar to Fire King, but I don't know the details. The bluish, partially translucent areas are beautiful, and I wanted to keep them, but I haven't had a chance to use them, so I've decided to sell them. They have never been used since I bought them. The discoloration was present from the time of purchase. Please check the condition in the photos, and this is for those who understand vintage items. Thank you for your consideration.
