Our Humidity Indicator Card will be helpful in judging if the package is safe to the product, indicating if the desiccant inside the package remains valid or needs to be replaced. The humidity indicator dots will change from blue / brown to pink / light green as the relative humidity increases in the volume of air surrounding the indicator. The humidity indicator dots are reversible, and the pink / light green dots will change back to blue / brown when the volume of air is dried. So, when open the package or container, if the humidity indicator dots are blue, it shows that the product is well sealed and in safe conditions.
