This slate coaster features natural color with rough edges for a truly unique and rugged look that is sure to compliment your home on your coffee table, bar, or countertop. 4 soft EVA pads underneath the coster avoid scratches on surfaces. Unique characteristics from one piece to the next are a mark of the quality and natural beauty behind each product. Permanent etching allows this coaster to have zero maintenance. Simply wipe with a damp cloth to clean. Air circulates into the slate and evaporates the liquid, drying the stone back out quickly. Ideal gifts for parties, weddings, celebrations, holidays and more. A set of 4 pieces with bamboo stand is also available. Please request detailed pricing.
