Description from KonMari
Made of diatomaceous earth – a type of sand made from fossilized algae – this soap dish is as organic and unadulterated as it gets. Exceptionally absorbent and breathable, it makes an ideal landing pad for soap, keeping it clean and pristine (read: no melted, gooey soap scum!). Add it to your tub for all-natural earth vibes
Dimensions: 4″ Dia x 0.5″ H
Care & Use Instructions: Rinse quickly with water and dry. For stains, use a soft brush to rinse, or treat with light bleach and rinse. If you notice a decrease in absorbency, a quick rub with sandpaper will restore it to its original state.
