Reusable moisture absorber ideal for placement in your car, as it prevents fogged windows and the growth of mold. It reduces humidity both in the cabin area and in the luggage compartment, wherever it is chosen to be placed.  

It has a humidity indicator, which changes from brown to blue when it has absorbed enough moisture, meaning when it is full. To make it usable again, place it in the microwave, oven, sun, or heater until its moisture is completely evaporated and the color of the indicator changes from blue to brown.
