Beautiful, elegant Blue Lagoon nebula bloom coasters in shimmering blues, red violet, purple and gold are the perfect compliment to any kitchen dining area. Set of 4, 4" diameter coasters are on an acrylic base with a cork backer and a thick glossy resin coating to protect from spills and heat. It is highly recommended to wipe clean with mild detergent and a damp cloth, no dishwasher, no immersion, to protect cork backing and prevent scratches on the glossy surface. One of a kind design created with the bloom technique so every single one, even in a set, is unique and special. Sets are paired in like designs using the same color batch.
