NLXL wallpaper is printed upon order. Please allow 3 - 4 weeks to ship out and receive tracking. From the Materials collection designed by Piet Hein Eek for NLXL: "A lot of companies have made marble reproduction products, but never in the way we envisioned it. So we decided to give it a try. When the printing proofs came in we had the exact same thrill as we had five years earlier with the Scrapwood Wallpaper. You just want to install it everywhere." After the worldwide success of Scrapwood Wallpaper, Piet Hein Eek and NLXL introduce "Materials", comprising 8 contemporary designs.
