These large coasters protect your home's surfaces from spills, stains and everyday messes. They're low-profile to help prevent tips and tumbles. Plus, the anti-skid finish and no-slip nibs on the bottom keep whatever you put on them in place. An outer lip also helps contain condensation, drips and leaks to defend your tabletops, countertops, floors, outdoor patio and more. Simply wipe them down or pop them in the dishwasher. Choose from three different sizes, two shapes, and four colors. Each set contains four (4) coasters.
