Eco-Coasters Set of 4
This colorful coaster set is made of a super-absorbent, eco-material called diatomite. The diatomite is a single-celled algae found in plankton in the ocean, which is accumulated after it dies and then fossilized after hundreds of millions of years. Bring this beautiful and interesting material to your home with this handful set of coasters. Why not tell your guests the story behind your cool diatomite coasters?
