Place your preserved roses indoors, out of sunlight and never water them, as they do not need water to stay fresh. Additionally, your preserved roses will stay fresh longer if they stay in a location with relative humidity between 30-60%.
If covered with dust, use a hairdryer on low temperature and low speed settings from 2 feet away to gently blow off the dust. If the petals are too heavy due to moisture, please place the product together with the desiccant in a sealed container for 3-5 days, then put it back in its usual place.
