The result of two years of research, this washable sponge has become the brand's bestseller since 2019. The sponge consists of one side of organic wool, solid and scratchy; of an organic cotton in a honeycomb providing an absorbent side and of an organic cotton fleece core, for good absorption. Thanks to its technical sewing, with organic cotton thread, the sponge is maintained over time and the padding does not move. It will wash dishes perfectly without scratching surfaces, and the link allows it to be hung up after use to dry. The sponge is bigger because it will shrink during the first few washes to take on the size of a conventional sponge. The wool will felt, which will allow it to be solid over time. Available colors: gray and dark blue Compostable at the end of life, after about one year of use. Each sponge goes to 30° or 40° in the machine, in a short cycle, and loves to dry under a light sunny breeze. Never put in the dryer.
