Made with natural sandstone, so there are natural irregularities. Sandstone is naturally absorbent and durable. Each of the four coasters has a different petroglyph etched into the surface and a cork backing to protect your furniture. They all fit nicely into the wooden holder and look beautiful when displayed, but are practical to use.
One coaster has a very small tear in the cork backing. Please see the last image to view this defect, otherwise no nicks, cracks, chips or repairs noted. Please see all pictures, as they are considered part of the description.
