These cool new Concrete Hexagon Coasters have unique hexagonal patterns that act as conduits to wick condensation away from wet glasses and cork bottoms to protect the table. They're made from a unique mixture of concrete that uses extremely small particles and very little water to create an incredibly strong, smooth, and tactile surface and then are finished with two coats of carnauba wax to resist staining. These hardcore, heavy duty coasters come in a set of four.
