At Studio Decorai, all coasters are made of MDF with laminated artwork on the top. Each coaster measures 3.5”x3.5” with rounded corners. The base is made of polished wood. Our coasters are made of high-quality sustainable medium-density fibre boards. Each coaster is handmade in our studio and covered with a water-resistant lamination for the longevity and protection of our artwork. The base of each handmade coaster set is made of polished pine wood.
