All my wipes are made of cotton and bamboo sponge. They are completely in an eco-responsible approach, because they are washable and therefore reusable. To keep them dazzling white, you can pre-wash them with Marseille soap and soak them overnight with sodium percarbonate, available in organic stores. They can be used by the whole family (washcloth, baby's buttocks, cleaning the eyes of animals ...). Some sets are equipped with loops to facilitate makeup removal.
