This soap saver is made of a multi-directional bioplastic, which allows water to drain and air to circulate. This keeps the soap dry so that it will last longer.
We use them at our kitchen & bathroom sink, plus our bathtub. It helps keep the soap from melting onto the surface it's sitting on.
The size of the soap saver is 4.8 inches x 3 inches in length, but can be trimmed to fit any soap dish or space.
