These loofah sponges offer an exfoliating texture, are easy to hang, work with any shower gel, come in white color, and are a smaller, more compact size for less waste. They use a hanging knot design, making every bath sponge core firm, durable, and not likely to fall apart. The design makes it easy to dry, and easy to store. Simply hang on a shower hook or caddy in the shower to store/dry. They are made of mesh material, and are approximately 4" in diameter.**
