Purchased in France. Approximately 23.5cm x 23.5cm. I believe it is Sarreguemines, but as there is no backstamp, please refrain from purchasing if you are particular about the maker. There is a kiln mark in the 8th photo. In the 9th photo, there is a chip-like or kiln mark-like area that appears to have been present since manufacturing. I believe it is in near-unused condition with no signs of use. NO.5248
