This is a glass plate by the popular artist Tokiko Kurokawa. I purchased it in Tokyo some time ago. The color is gray. It's not a transparent gray, but it's a beautiful color, not a heavy gray. There is a white line on the edge. The front has a thin white line, and the back has a slightly thicker white line. *Please refer to photos 4 and 5. It's an easy-to-use plate with no depth. There are no cracks or chips. *Measurements are approximate. For reference only. Height: Approximately 1cm Diameter: Approximately 21.5cm
