This set of six Round Cork Coasters will add a nice, natural accent to your home. Cork is obtained from the bark of cork oaks, which regenerate themselves, and is extracted without damaging the tree. Portugal is the world’s largest producer of this material, which has extraordinary characteristics: lightweight, water-resistant and absorbent, and used for thermal and acoustic insulation. It also has a naturally beautiful appearance. They’re sourced by A Vida Portuguesa, a small women-owned, Lisbon-based shop  focused on goods made in Portugal. Each Round Cork Coaster measures 3.3”diam.
