Natural sponges have been used for bathing for thousands of years and are still prized for their beauty, durability and utility. The natural sponge is a renewable natural resource that is harvested from the ocean and comes in a variety of colors, shapes, sizes and textures. Sea sponges are extremely earth-friendly. Natural sea sponges are truly 100% natural from their unhampered-with cellular structure, to their naturally occurring sea minerals, to their eco-processing. They’re fully biodegradable. Their sustainable harvesting with minimal waste has also been shown to promote the growth of sponge colonies and enhance the ocean’s ecosystem. Scientific studies have consistently confirmed that the regular harvesting of natural sponges actually enhances the health and population of the sponges.
