NLXL wallpaper is printed upon order. Please allow 3 - 4 weeks to ship out and receive tracking. Internationally renowned Dutch designer Piet Boon and his multidisciplinary Studio Piet Boon team, frequently travel the world meeting new people and experiencing different cultures. Their travels enable them to draw creative inspiration from a variety of unique (design) projects, cultural impulses and new materials such as the extraordinary Japanese Washi paper. Washi, meaning Japanese paper, is traditional handmade paper of which its rich history dates back to 610 AD. Though the paper nowadays enjoys a contemporary following used for different purposes, it still holds the same characteristics of strength, durability, lightness, warmth and flexibility as the traditional version. Impressed by the paper' characteristics, versatility and beauty, Studio Piet Boon used it as an inspiration for the new Piet Boon® Wallpaper design: a modern interpretation of Japanese Washi paper. 19.2" W x 32.8 feet L - Approx. 52 square feet per roll.
