Called "black diamond," it has a absorption capacity 4 times greater than conventional charcoal. Thanks to its walls with microscopic cavities, it is not only able to absorb what needs to be absorbed (humidity, bacteria, pollutants, etc.), but it is able to render what needs to be done if necessary.
This is very useful for regulating the humidity of your refrigerator, now guaranteed odour-free.
Ditto in sneakers, and any shoes. No need to get upset when Claude comes home from his jog and he stinks of feet. Leonore even has bamboo charcoal-soaked soles to offer.
