Say goodbye to water rings on your table tops. Arriving as a 4-piece set, this coaster is a stylish solution with a fun pattern we love. Made from wood, it features colorful triangular shapes that resemble a mountain range as an orb (the sun or the moon) floats in a white sky. Hues range from red and blue to brown and gray for a standout accent that serves a dual purpose as surface protector. Each coaster is octagonal shaped but closer to a square in surface area.
