This handmade set of four coasters are made of clear glass with individually handmade green fused glass swirled pieces fused to them.  Each coaster is five inches square, with a dropped center circle to prevent any liquids from spilling off of the edges.  These decorative and functional pieces are food safe, but should not be put in the dishwasher nor in the microwave.  The price is $44.00 for a set of four coasters.
