Large Fridge Coasters are designed for the refrigerator and outperform everything else by working properly anywhere you place them in your refrigerator. They perform three specific tasks. First they provide a breathable layer between your produce and the hard plastic crisper bin surface. Second they absorb moisture and dry completely while still in the fridge ensuring you never have to scrub your crispers ever again. Third they stay put, made from rigged hard pressed wood pulp they are not going to slide around or get bunched up when opening and closing drawers.
