This collection is a trademarked, non-sticky, dust resistant formula which creates the illusion of botanical in water. Although "silk" is a common term used to describe artificial botanical, flowers and foliage, the Primrue floral designs are actually made of materials that have more durability and do not fray or fade as silk does. Particular botanical components are individually wired and specially crafted to maintain realistic form, while the subtle coloration, shadings and striations in the natural botanical are duplicated to perfection! Cleans easily with a duster or dryer on cool setting; made in the USA of imported components.
