NJ Lighthouses. Unique Jersey Shore coasters. One of each or you can customize the set with other lighthouses. Just let us know. Each coaster made by Dreamweaver takes on different appearances due to the underlying marble tile which has its unique veins, pitting and marbleizing. The beauty of the marble shines through giving it a beautiful weathered look. Each coaster is backed with a cork backing to absorb moisture and protect furniture.CARE: Wipe with a damp soft cloth. Not dishwasher or oven safe. Have an idea of something you would like on a coaster? Custom orders always welcome.
