This 100% natural sponge has a soft texture, a natural facial and body cleansing sponge made out of vegetable fibers of Konjac root.The Konjac Sponge has been used in Japan first as a bath sponge for newborn babies for more than 100 years because of its soft texture. Due to the popularity the Konjac Sponge has been on the rise as facial cleansing and bath sponge in China, Southeast Asia and Europe.These Konjac Sponges have a unique propriety layer that can hold water very well. When the sponge is saturated with water, its surface is covered by a water layer.
