This glorious tableware -- coasters, bottle holders and trivets -- is made of a modern material (silicone) but refers back to the artistic legacy of past civilizations. Each piece is 100% handmade and is truly a little art treasure on the table. Patterns and colors are designed to compliment and contrast each other just like mosaics of ancient times. You can mix and match the objects to create an even more complex presentation. 100% waterproof and washable with soap and water.
