Self-drying Soap Dish is made of 100% renewable material named Diatomite (fossilized algae, hence plant-based). It's water-absorbent and quick-drying which makes it ideal to place on the kitchen and bathroom counters where water can accumulate without frequent clean-up. The soap tray's finish is similar to concrete but with draining holes and pathways which will ensure soap and shampoo bars dry and your countertops and bathtub ledges are clean from soap residue. Care Tips Please refer to the last product image. Disposal Repurpose the dish tray for gardening, crafts, and other creative projects.
