These silicone body scrubbers have soap dispensing functions. Before using, open the lid on the top of the scrubber and fill in with proper amount of liquid soap. When the liquid soap is needed, just gently press the sides of the scrubber, it will flow out from 4 tiny holes at the bottom. Once filled fully it can last up to 1 week. Very easy to refill, the body brush has better cleaning effect and high efficiency.
