Coasters for your car. Our sandstone cup holder car coasters fit perfectly in your existing cup holder, and will soak up any extra moisture from your beverage! Approximately 2.5" in diameter by 1/4" thick, with a divot for pulling back out to clean when necessary. Imprint will not fade or scratch off, so these coasters will look great for a long time to come. This is 1 car coaster, not 2 as shown in the picture.
