Moisture absorber suitable for use in security cases. It is used to protect the contents of the cases from moisture, as its construction absorbs and traps internal moisture. 

When the indicator window of the absorber changes color from orange to green, the absorber needs reactivation. Reactivation is done by placing the absorber in the oven for three hours at 120°C. After reactivation, the color of the crystals turns orange again. The metal casing of the silicone crystals is made of aluminum. It contains silicone crystals and is reusable.
