This set of 4 handcrafted School of Fish Drink Coasters by McCarter Coasters is both practical and attractive. The fine textured detail is embossed to give each piece a rich dimension. Created from highly absorbent all-natural bisque clay, the porous nature of this product naturally drains condensation from drinks while the cork feet protect furniture. All the moisture disappears and the coaster will never stick to your glass. These 4.25" beauties are the most absorbent coasters on the market and the natural color is well suited for any décor. Clean with any mild bleach product.
