Absorbent Coasters. Relax at the Beach II - Single Absorbent Coaster - It features a beach scene where it looks like two parents are in beach chairs, enjoying the sunshine while their children play off in the distance. It says just a single word, "Relax." 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.
