Each coaster features thickened felt padding for superior water absorption and heat insulation, capturing liquids before they reach your table surface. The four soft anti-slip pads protect your furniture from scratches while preventing cups from sliding, and the high-quality felt won't stick to glassware when lifting your drink. Built to last, these reusable coasters are sturdy and drop-safe, with flat, stackable surfaces for keeping your tabletop organized and refined.
