This stylish little dehumidifier will keep all your clothes and bedding fresh, dry and mildew-free in confined spaces such as closets, chests of drawers and storage benches. The ceramic egg contains silica crystals that naturally suck excess moisture out of the atmosphere, leaving the air at a well-balanced level of humidity. No batteries are needed and it costs nothing to run. When the crystals are full, the panels on the holder turn from blue to pink. Simply remove the egg from its holder and pop in the microwave for a couple of minutes to dry it out. Place it back in the holder and the panels will return to blue, the egg fully 'recharged' and ready to use over and over again.
