Product number: 4009463801106 View all from Croll & Denecke > View more: Natural Sponges > A natural sponge is a simple life form found on the bottom of all oceans. 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 over 7,500 different types, only 6 of which are suitable for sale. Some grow to more than 3 meters high! Depending on the temperature, depth, and current, a sponge needs half a year to five years to grow. Natural sponges are wonderfully soft for the skin, can absorb a lot of water and release it easily (by squeezing it). 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, whereas with a natural sponge, all channels have an outlet, allowing dirt to be 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.
