Fine art ceramic coaster. Scratch resistant matte surface with cork backing. The coasters have sharp details and vivid color. They are 3 7/8" square. Many of the images come in sets. If there is shown a themed set of four, each coaster must be purchased separately. You can search for your favorite subjects. Mix and match any combination of coasters to create your own matching or custom set. I also offer each of the images in fine art prints. Visit www.finewatercolors.com to see more available art.
