Sponge + Drink Coasters = SpongeCoasters.

If your drinking glass really sweats won't the SpongeCoaster absorb the liquid to the point of saturation thus allowing the liquid to soak through to the surface it's sitting on? I don't see anything to prevent this from happening. Even if there was a protective cover on the bottom the liquid would eventually escape from the sides and drip down to the surface it's sitting on. I doubt if I'd buy this product.
