The province of Limburg is famous for its marl caves and pits. Marl is traditionally used in buildings and statues. Maastricht-based Tess Cleven took a closer look at this chalky material and found it to be easily grindable, very porous, and a great absorber. ‘Living Stone’ comprises three wellness products that make clever use of these characteristics. An all-natural Scrub gives your skin a healthy boost. The Scent Stone will take in any flavoured liquid and give off its fragrance for weeks. And the De/Humidifier is able to adjust the indoor humidity by absorbing or evaporating water from or into the air.
