Our modern and chic hexagon marble coasters fit perfect in any decor! These make a great birthday, housewarming, graduation, man cave or Christmas gift! Our marble is thick and heavy. A very classy coaster for any room. Each coaster roughly measures 4" x 4" (4" from point to point) x 3/8". There are protective cork feet on the bottom to protect surfaces. Coasters are leveled so they do not teeter. Our coasters are made from natural marble and are free of sealants. Each design is hand-stamped with permanent ink that will not fade. Each piece of marble is unique and the veining colors may vary. Spot clean with soap and water.
