Minimalist. Clean. Absorbent. This water-absorbent soap dish is made of hardened diatomaceous clay (sand derived from fossilized algae) and would be a modern addition to any bathroom. Why Soap Dishes? Aside from being a beautifully minimalist bathroom decoration, our soap dish serves an important purpose. Since our all-natural cleansing bars don’t contain any chemical preservatives found in liquid soaps, this water-absorbent soap dish will prolong the life of your Aureline bars by keeping them dry, pristine, sanitary, and ready to use each time.
