Water Absorbent Concrete Coaster

Don't just prevent condensation rings on your tables, absorb them and watch them fade out of existence like rain on a cracked sidewalk when you use these cool new Concrete Coasters. These heavy duty coasters are made from cement combined with non-toxic recycled ash to make them ultra water-absorbent and heavy enough to prevent them from sticking to your glass. They may be stylishly cracked, but that adds to their hardcore functional charm.
