This listing is for two beautiful super nova ceramic tile coasters, mugs are not included. This set of two granite coasters match each other, and the very dark blueish black background has gray swirls with a few orange flecks. This pair of coasters are perfect for protecting your coffee table, relaxing outside on the porch, or keeping on any other surface where people may set their drinks down!
Each tile measures approximately 4x4 inches and is about 3/4 an inch high. The upper surface is waterproof, but please do not submerge in water. In order to protect your surfaces, there are four felt circles on the bottom. These are not visible from above and make the coaster rise above the table, which is why we are the "floating" stone!
