These artificial calla lilies are super easy to use. You can place them in vases to decorate your home, or use them at weddings, parties, and other events. Just arrange the stems as you like to create a beautiful floral display. When it comes to maintenance, it's quite simple. You can use a soft brush or a hair dryer on a cool setting to remove any dust that might accumulate over time. Be gentle when handling the flowers to avoid any damage to the delicate poly foam petals. Also, keep them away from sharp objects to prevent tearing. Store them in a dry and cool place when not in use to maintain their shape and color.
