NLXL Materials Wallpaper PHM-50B Tiles By Piet Hein Eek arrives after the worldwide success of Scrapwood Wallpaper. Again this collection creates a magnificent trompe l'oeil effect. A lot of companies have made marble reproduction products, but never in the way you'd envisioned it. So NLXL decided to give it a try. The imagery for marble wallpapers came to life after being scanned from old buildings in Amsterdam.
