Responsibly harvested natural silk sea sponge from off the coast of the Philippines for gentle face exfoliation with mineral benefits. Use wet sponge on soapy skin to gently buff away dead skin cells and dirt. The minerals contained in sea sponges nourish and benefit skin. These include, but are not limited to: calcium, magnesium, sodium, iron, zinc, and potassium. Simply rinse and hydrate. Natural Sea Sponges are a renewable resource. When sponges are harvested, the sponge divers hand cut each sponge to ensure that more than one inch of the base remains intact. The sponge then re-grows back to its original form within 3-5 years. Studies show that areas harvested actually increase the population density of sponges. We have partnered with a family owned and operated company. 1 sponge per box. Sponges naturally vary by size and shape.
