Rated 2 out of 5Â by jstand6 Does not absorb moisture through map print
I purchased these Thirstystone coasters for their ability to absorb moisture -- specifically condensation that forms on the outside of a glass containing a cold drink. The old world map print on the top, which does look very nice, prevents the stone from absorbing any moisture. This totally defeats the purpose of this type of coaster. I suppose it will absorb moisture if spills over the edge slowly, but the pooling of moisture on top ends up dripping off of the glass as you lift it. I am very disappointed. But there is a lesson learned here: Don't buy Thirstystone coasters with any type of print on top!
