WeatherTech Coasters protect your precious surfaces by fusing style and strength in the ultimate protection against spills, scratches, watermarks and heat burns. The state of the art surface protectors feature the very same raised lip design and environmentally friendly, TPE material featured in WeatherTech All-Weather Floor Mats. Featuring a textured pattern that prevents slippage and sticking while small stubs on the underside allow for essential airflow between the coaster and the surface. They are even self-stacking for easy and convenient storage. Unlike some coasters made overseas, these are odorless! You will wonder how you ever lived without them. Proudly made in Bolingbrook, Ill USA!
