Created exclusively for the Fine Arts Museums of San Francisco, this absorbent sandstone coaster features Claude Monet's Water Lilies (detail), ca. 1914-1917, and is the perfect way to bring the Legion of Honor's permanent collection home. The stone coaster lets condensation sink in, keeping your furniture safe from staining and discoloration. If your coaster becomes stained, soak in hot water with a mild liquid detergent for 60 minutes, rinse thoroughly, and let air dry. For stubborn stains, use one part household bleach and three parts hot water and soak overnight. Measures 4 x 4 in.
