This set of 4 fabulous coasters feature 4 different designs (see picture) and measure approximately 3.5 by 3.5 inches. They are 1/8th of an inch thick and backed by durable neoprene rubber. The texture and material is similar to a small mouse pad. The coasters have a fabric surface which is heat resistant (perfect for coffee or other hot drinks). They are machine washable and fade resistant. The neoprene rubber backing on their underside prevents slippage and protects furniture and counter tops from scratching. This set makes a fantastic decorative accent to any kitchen, home or office!
