I purchased this item at an antique shop in America and have been collecting it. This is a small Fire King Primrose casserole dish. It is sold as a set of 2. Both pieces are a rare type with the markings upside down. There are some uneven spots like ripples on the bottom that occurred during the manufacturing process, and there is some discoloration near the edges of the handles. These are both characteristics of milk glass. Please check pics 6 and 7. There are no chips, cracks, or hairlines, and it appears to be in beautiful condition with an overall shine. I will sell it to someone who is looking for it. ※This is a used, old item. We are looking forward to your purchase if you understand the characteristics of vintage items and milk glass (^^) Approximate size W17.5cm (including handle) Inner diameter φ13cm H5.2cm Era Around 1960-1962
