Ideal for use with cold-pressed natural soaps. The sponges are sustainably harvested in the sea above the root so that every sponge can grow back. Natural sea sponges contain minerals such as potassium, zinc, iron, sodium, and magnesium. They also gently exfoliate your skin, removing dead skin cells. They contain a natural enzyme that blocks the growth of bacteria. This, in turn, inhibits the odours associated with artificial sponges and ensures they are anti-bacterial. Available in various sizes: Very Large: 8″, Gigantic: 10″. Made in Greece.
