Absorbent Coasters. Relax at the Beach III- Single Absorbent Coaster - There is a picture that appears to be painted on the face of the coaster that shows a family enjoying the bright sunshine on a calm beach. The only word on the coaster is, "Relax" in large white letters. The porous coaster surface absorbs small drips before they reach your furniture. It measures 3.7" square, has a cork back, and wipes clean with damp cloth. This will make a great addition to any surface that needs an absorbent coaster.
