• 3.94" x 3.94" white sandstone coaster with cork backing
• Sandstone is softer than ceramic, which allows it to absorb liquids more quickly and hold it until it evaporates
• Smooth, natural finish

• To clean your sandstone coaster, run under warm water and scrub lightly as soon as the staining liquid comes in contact with coaster.  For stubborn stains, you can apply a few drops of mild detergent and lightly scrub the coaster with a sponge or brush and then allow to air dry
