The color is gray. This is a set of two. The size is 21cm. Purchased from an authorized store in California. There is a slight dent in the 3rd photo, ↘︎ part, but it was there from the time of purchase. I purchased several of the same dinner plates, but I am selling them because I have too many. Although they are new and unused, please understand that they have been stored at home. Different colors are also available. We will offer a discount if you purchase them at the same time.
