Rainbow Coaster Set
Start each day with a different blend of artful colors. After a cup of coffee or a glass of water, you can stack this set-of-four coasters vertically in order to transform them into a light-based work of art. Light shines through the transparent coaster to create a lovely glow. Stack coasters together in endless combinations to blend them into unique, multicolored rainbow gradients. The set comes in four coasters of distinct colors: red/pink, yellow, green, and blue.
