Local sponge" usually refers to a traditional African bathing sponge known by various names in different regions, such as "Sapor" in some West African countries. It is a mesh-like sponge made from plant fibers and is known for its rough texture, which makes it effective for exfoliating the skin during baths. The sponge is elongated and often has a net-like appearance. Many people in Africa prefer using this traditional sponge over modern bath sponges because of its exfoliating properties and its ability to create a rich lather with soap. Over time, with consistent use, it's believed to help in achieving smoother and clearer skin.
