NIVA design decorative wallpaper. NIVA re-dresses the walls of your home with nature. A collection of wallpapers inspired by traditional artistic techniques. Flamingo is inspired by acrylic tempera painting, while the tropical fruit of the Costa Rica series is made with the graphite technique. All the handmade decorative motifs are digitized and printed on washable flame-retardant paper or on a PVC surface intended for public spaces or hotels.
