Absorbent Coasters. Beachin' Time - Single Absorbent Coaster - On the face of this coaster, there are the words, "Livin' on... Beach Time." Under the words, there is a coconut drink. 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.
