Coasters are one of those things many people do not think about today but they should. They protect the surface of tables from scratches and ugly stains. When wood tables come into the picture, there is no question that coasters are a must. The condensation from glasses or mugs can do permanent damage on wood surfaces. These heart shaped coasters are made from slate and will add to the room decor. Share the love with our heart shaped set of four natural slate coasters. Warm someones heart with these coasters. A lovely gift for them to place their beverages.
