Konjac sponges are a natural way to exfoliate the body’s largest organ. These Konjac exfoliating sponges are hard until softened with the addition of water. They deep cleanse and gently exfoliate the skin. Reusable and have strings to hang for drying too. This lovely set couldn’t have come at a better time for my winter skin. My gift to my self this season of giving. It would also make a lovely gift too for any occasion.
