This is a ceramic coaster in the shape of a cat, made of diatomaceous earth-like material. Cork is attached to the back. Size: Diameter: approximately 10.5cm Height: approximately 5mm Diameter of the area for placing a glass: approximately 9cm Although it is new and unused, there are some dark spots on the unglazed back due to long-term storage. I apologize to those seeking perfection or who are very particular. I have tried to photograph any areas of concern, but there may be some oversights. I apologize if the color is different from the image, as I was unable to photograph it well. There is no box, so I will pack it with cushioning material before shipping. Thank you. #coaster #diatomaceousearth #cork #cat
