These cool new Chalkboard Slate Coasters not only save your furniture from condensation rings and drips, they also make it clear whose drink is whose. This set of four coasters are made from chalkboard slate and include two pieces of chalk for writing down the names of guests, jotting down phone numbers, practicing math equations, or just for sketching out an ingenious invention idea. They clean up easily with a chalkboard eraser or a damp sponge. Great design.
