In the sea, the sponge acts as a filter. It pumps water through itself, and in this way a sponge obtains nutrition (such as plankton). There are more than 7,500 different types, of which only 6 are suitable for sale. Some grow to more than 3 meters high! Depending on the temperature, depth, and current, a sponge takes six months to five years to grow. Natural sponges are wonderfully soft on the skin, can absorb a lot of water and easily release that water again (by squeezing them). The fibers of a sponge are very similar to silk, and sponges have been used by people for washing themselves for ages. A synthetic sponge has closed air bubbles, while with a natural sponge all channels have an exit and through which dirt is easily removed. A natural sponge is therefore very hygienic, and recommended for people with allergies or sensitive skin. NB: a natural sponge should not come into contact with boiling water. If it is necessary to wash the sponge, it can be done in the washing machine (in a laundry bag) on ​​the wool program.
