The non-withered flowers can be stored for more than half a year to more than three years due to special processing. There is no fragrance and pollen after processing, so there is no need to worry about allergies. 1. Avoid placing it under high temperature and humidity, direct sunlight or strong lighting. 2. If dust accumulates on the flowers, use a soft brush or hair dryer to remove it.
