"PVA Sponge (Polyvinyl Alcohol Sponge) is a super-absorbing synthetic material with excellent water retention rate. With its open-cell and fine texture, this sponge is soft and gentle to every skin type. It is ideal for facial cleansing. PVA sponge is hardened when dry. Once wet, it is soft and absorbent. Simply immerse in water to regain its softness."
