Cork-back coaster is a type of drink coaster designed to protect surfaces from heat, moisture, and scratches. The cork provides a non-slip grip, preventing the coaster from sliding on smooth surfaces. It also acts as a cushion, reducing noise when placing drinks on the coaster and providing additional protection from condensation or spills. The natural properties of cork — being lightweight, water-resistant, and aesthetically pleasing — make it an ideal choice for this application.
