The size is as shown in the photos. I purchased this item, a different size, from the pottery shop I always use. It's too big for my border collie. I used it as a water bowl, but I've decided to use something else, so I'm putting it up for sale. It's from a pottery shop along the national highway near Nara and Iga. I think the quality is good. I use other items made there. The bottom is bowl-shaped and heavy, so it doesn't move. The black spots on the inside of the bowl look unsightly, but they are part of the pottery's surface. They are not dirt.
